How Do I Handle Problems When Pushing Messages?

When you use REST APIs to push messages, you may encounter some problems. In case of any problem, locate the fault following the instructions below:

Check whether the message push API URL (https://push-api.cloud.huawei.com/v3/[projectId]/messages:send) is correct.
- Use the push API URL of the V3 version. Do not use the push API URL of V1 or V2 version. For details, please refer to Request URL Version Problem in a Scenario-Specific Message.
- Check whether the projectId in the push API URL is the same as the ID of the project to which the current app belongs. If not, update projectId in the push API URL, regenerate a JWT, obtain a new push token, and then push the message again.
If the message push API returns an error code, rectify the fault by referring to Service Response Codes.
If the message push API is successfully called but the message is not displayed on the target device, rectify the fault by referring to Why Does the Target Device Fail to Receive a Push Message After the Push API Is Successfully Called on the Cloud?
