Platform Authentication Rule

  1. Telebirr platform allocate appId and appKey to the corresponding third party client. Each third party will have a unique appId and appKey.
  2. Third party source IP addresses should be added on the trust list. Those IP addresses of clients that are not in the trust list will not access telebirr system.
  3. The time of the timestamp is consistent with that of the server (within one minute). If they are inconsistent, the access is considered illegal.
  4. Check whether the signature entered by the client is consistent with the signature generated by the system. If they are inconsistent, the access is considered illegal.
