  14. 14. BusinessConnect Development How-To and Key Points ©LINE Corporation 14
  15. 15. BusinessConnect Development How-To ©LINE Corporation 15 What to Do Before Starting Development You need to complete the following steps before starting development. 1. Obtain BusinessConnect server and SSL certification, and set up event endpoint URL 2. Submit completed “LINE BusinessConnect Account Creation Application” to LINE. 3. Create BusinessConnect Channel and Account (done on LINE side) 4. Complete preparations to receive event requests from BC server. -Have received requests return the status code 200 (explained later) 5. Friend account to check whether requests are being properly received by the BC server. 6. Begin development. Please check to see that you’ve received the following LINE-issued materials before beginning development. Materials Provided by LINE • LINE BusinessConnect Service Introduction Material • LINE BusinessConnect Operational Guidelines (this resource) • LINE BusinessConnect Server Security Guidelines • LINE BusinessConnect Security Check List • LINE BusinessConnect LINE developers Manual Documents Sent by You • LINE BusinessConnect Account Creation Application • LINE BusinessConnect Resource Check List Materials Provided by LINE * Event endpoint URL Endpoint URL used when sending requests from GW server to BC server.
  16. 16. What to Do During Development ©LINE Corporation 16 A) Creation of Connection with GW Server - Returns HTTP status code 200 (OK) to received requests. - Automatically updates Channel access token, B) Secure Connection and Server Environment - SSL-based connection. - Environment constructed according to Security Guidelines. C) Preventing Invalid Requests from Sources Outside of LINE - Signature validation of received requests.(Signature Validation) D) Measures to Handle Large Concentrated Request Volumes - Hold stress tests to check durability against large access volumes. E) Other Important Points - Processing of single requests containing multiple events. - Handling duplicates when messages resent. We ask that companies utilizing BusinessConnect create, at a minimum, the systems below in order to protect user information and to ensure smooth communication with users through LINE.
  17. 17. A) Proper Network Connection with GW Server ©LINE Corporation 17 A-1. Returning HTTP Status Code 200 (OK) to Received Requests Please first set up the BC server so that it promptly returns the status code 200 once receiving a request. Please aim to have status codes returned within 1,000 milliseconds (1 second). If a response is not sent within 5 seconds, a slow response error alert will be triggered, and if a response is not sent within 10 seconds, or a response other than status code 200 is sent, the request will be resent by the GW server. We recommend the following setup procedure to ensure prompt and accurate status code responses. A-2. Automatic Refreshing of Channel Access Token When a request is sent from you to the GW server, the GW server will authenticate each request using the Channel access token issued to each Channel and contained within the request header. An expiration date is assigned to the Channel access token, and you will no longer be able to send requests once this access token has expired. Therefore, please construct the BC server so that it regularly and automatically refreshes the access token. * Please refer to the RESTful API’s Reissuance of Access Tokens for API reference on refreshing access tokens. Recommended Procedure 1. Receive JSON request on BC server. 2. Enter JSON content into DB, memory, etc. 3. Return status code 200 to GW server 4. Conduct signature validation, duplicate checks, etc. (explained later) 5. Individually process event within code if request is successfully validated as per item 4.
  18. 18. B) Secure Network and Server Environment ©LINE Corporation 18 B-1. Network Environment Supporting SSL BusinessConnect requires that the network environment between the GW server and BC server supports SSL. In addition, as we do not support self-created certifications, please ensure that you procure an SSL certificate from the relevant agency in advance of registration. B-2. Network Constructed According to Security Guidelines The following materials contain the security standards required when implementing the BusinessConnect service. We ask all developers to abide by the security guidelines contained below and to prepare an environment that meets or exceeds all security standards before beginning development. • LINE BusinessConnect Server Security Guidelines LINE BusinessConnect Server Security Checklist SSL GW Server BC Server
  19. 19. Via GW Server C) Preventing Unauthorized Requests Not from LINE ©LINE Corporation 19 BC Server A signature is included in sent requests. The BC server calculates a separate signature using received request signature, and checks to see whether or not this signature matches the one contained in the header in order to validate it. Please see relevant documents for how to calculate signatures. Signature keys (channel secret) can be checked from the LINE developers website. Please take ample care in handling signature keys, etc. so as to avoid unauthorized access. Via Server Outside LINE ? Authorized Request Unauthorized Request Match No Match Process request as normal. Dispose of without processing. C-1. Signature Validation of Received Requests API API Message from LINE App Unauthorized Access Calculates separate request signature to check validity of header signature.
  20. 20. D) Countermeasures Against Large Concentrated Access Volumes ©LINE Corporation 20 D-1) Implementation of Stress Tests that Assume Large Access Volumes One special feature of LINE-based media is that user access may sometimes greatly increase over concentrated periods. Such circumstances may lead the BC server to become inundated with requests it cannot fully process, resulting in delays or the inability to send out response messages. Please conduct stress tests during the response message development stage and take necessary countermeasures against such concentrated access volumes. Please also inform us of the following information before and after implementing a stress test. • Expected Maximum Access Volume • Test Method • Test Results (Average response speed, occurring errors, etc.) Caution ・No stress test environment is provided from the GW server, so please prepare this on your side. ・If the BC server is unable to fully handle all received requests, the GW server queue may also become inundated with requests unable to fully processed by the BC server. If the GW server becomes heavily inundated with such requests, this may negatively affect other Channels, and in such cases we may have no choice but to delete backed up requests. • Right after account is released. • Right after releasing sponsored stickers. In terms of peak time periods, access volume tends to spike around 12 noon and between 5 pm and midnight each day. Circumstances Where High Access Volumes are Likely • Right after sending batch message to users. • When covered by news, in TV, or other media.
  21. 21. E) Other Important Points ©LINE Corporation 21 E-1. Processing of Requests Containing Multiple Events E-2. Handling Duplicate Processing of Resent Requests Requests do not always simply contain 1 event. When a large volume of messages are simultaneously sent, or a large number of users friend the account, 1 request may contain multiple events, and vice versa, so please construct your system with such multiple event-carrying requests in mind. If more than 10 seconds pass before the status code 200 is returned, the GW will likely resend the same request. If this resent request is processed as if it were the original request, the same message may be sent to the same user more than once. Please set up the server so that it is able to determine whether a request has already been processed, and disposes of requests if so. Recommended Procedure 1. Enter JSON content into DB/memory after receipt of request, then return status code 200 (refer to previous page) 2. Check Event “ID” attribute shown at the very top of the JSON code. 3. Dispose of data if the request has already been processed. * The “ID” attribute is also contained in the content attributes of message requests, so please ensure not to mistake it. The following points can also lead to system trouble if not handled properly in advance.
  22. 22. Recommended Request Processing Flow ©LINE Corporation 22 Disposal Resent Over 10 seconds pass Disposal Status Code 200 Returned [A-1] Signature Validation[C-1] Check for Duplicates(ID) [E-2] Relevant Operation/Message Processed LINE’S GW Server Your BC Server No Match Match Yes No Signature matches?

  23. 23. GW Server → BC Server Error Alerts ©LINE Corporation 23 When a request is sent from the GW server to the BC server and the BC server experiences some type of error, an error alert will be sent by email as well as displayed on LINE developers. Please check the causes of relevant errors promptly after receiving an alert, and take measures to resolve the issues. Email Recipients ・People with CHANNEL_EDITOR privileges under relevant Channel Roles within LINE developers. ・Mailing list registered as the Contact Mailing List Address under the relevant Channel’s Basic Info Page Subject [LINE Developers] BusinessConnect: Errors have been detected - <Channel Name> Examples of Error Notifications SLOW_RESPONSE (Response time > 5000ms) Sent when 200 response takes more than 5 seconds. Message response and other processing may be experiencing delays. REQUEST_TIMEOUT (Response time > 10s) Sent when 200 response takes more than 10 seconds. Message processing will be deemed unsuccessful and request will be resent. ERROR_STATUS_CODE 503 BC server may be unable to receive requests due to access overload. ERROR_STATUS_CODE 500 The BC server may experience an error for some reason. Error Reference Page<Channel_ID>/errors There are a number of other error types. Each alert signifies some sort of problem, so if received, please check to see what is causing the issue and take necessary measures to resolve it.
  24. 24. Related Features ©LINE Corporation 24
  25. 25. Sending Multiple Messages ©LINE Corporation 25 A Multiple Message feature exists that allows multiple messages (speech bubbles) to be sent in 1 request.

  36. 36. Frequently Asked Questions ©LINE Corporation 36
  37. 37. FAQ ©LINE Corporation 37 Category Question Answer Account Issuance Can an account be issued even if the endpoint URL has not yet been decided? Accounts cannot be issued in this case as no place to accept requests will exist. Accounts are only issued once the endpoint URL has been decided. Do endpoint URLs of test-use accounts also need https? We allow you the use of http for test-use accounts, but responsibility is placed on you for this decision. Is mailing list information required? Please include mailing list information if possible so that we can contact you if a mobile network issue occurs or to provide important information. Are secondary and tertiary points of contact necessary? Yes, these are necessary when registering for a real-use account. Handling Obtained Information Are user MIDs ever changed for any reason? A user’s MID will never change as long as they do not delete their account. A user will however be issued a new MID if they create a new account after deleting an old one. Is it possible to receive a list of all user MIDs who’ve friended my account? We do not provide MID lists. Can information on the number of friends be obtained? You can view this from the account manager page provided by LINE for official accounts. This information cannot be obtained via API. Can information on users who’ve blocked the account be obtained? Yes. An operation type called opType: 8 will be sent when a user blocks your account. What happens when messages are sent to MIDs of users who’ve blocked/deleted the account? The sent request will have a response returned to the BC server stating “successfully sent”, but the user will not actually receive it. Messages not actually sent are not included in the calculation of allotted messages used.
  38. 38. FAQ ©LINE Corporation 38 Category Question Answer Handling Obtained Information After receiving a block notification, exactly what is considered user information needing to be deleted? Information Considered User Information: User info (MIDs, nicknames, icon pictures, status messages) and user info obtained through chats (personal info, attributes, etc.), as well as chat histories received from users, etc. Information Not Considered User Information: Information obtained by user entry on your website after using a link, info saved in a format unusable to determine user identities, etc. Receiving Operations / Messages What is the maximum characters receivable in a message from users? There is a maximum of 10,000 characters. You stated that certain requests contain multiple messages, but when does this actually occur? How do descriptions look in such cases? Multiple messages may be sent together to reduce server load when users send a large volume of messages in a short period of time. The code will display as the following in such cases. {"result":[{1ST EVENT},{2ND EVENT}, ...]} Calling API What is the maximum number of MIDs that can be included in the “to” section of 1 request (the max. no. of users reachable with 1 request) Up to 150 MIDs can be included in the “to” section of 1 request. 1 MID counts as one message for billing purposes. When image, audio, and video content are sent, are these then stored on my server, after which the user accesses them? Correct. The URL will directly access the API designated URL to access content. However, data once accessed will be stored on the user’s device, so they will not re-access the same data unless they delete it first. How long does image, audio, and video content need to be stored on my servers? We cannot give a general response as this depends on how you intend to use such content. Users may not immediately access such content, so its best to store it for a certain period of time.
  39. 39. FAQ ©LINE Corporation 39 Category Question Answer Calling API Do old access tokens become invalid after updating the access token? Old access tokens become invalid after updating an access token through the API. Please temporarily stop sending messages and take other precautions so as not to cause errors after updating a token but before the new token setup is complete. Connection between Servers How fast are messages sent and received? We cannot give a definitive response to this question as it depends on the state of the talk, GW, and BC servers at the time. Is it okay to send responses to the GW server during stress tests? Please refrain from placing load on our GW servers during stress tests. Is it possible to create virtual user accounts for testing? Virtual user accounts cannot be created. Please contact the following email address for any additional questions.
