Why Does an API Failed to Be Called Across Domains?

  1. Ensure that CORS has been enabled for the API.

    Go to the API details page, click Edit, and check whether CORS is enabled. If it is not, enable it.

  2. Check whether an API with the OPTIONS method has been created. Only one such API is required for each API group.

    Parameters are as follows:

    API Group: The same group to which the API with CORS enabled belongs.

    Method: Select OPTIONS.

    Protocol: The same protocol used by the API with CORS enabled.

    Path: Same as or prefixally matching the request path set for the API with CORS enabled.

    Matching: Select Prefix match.

    Authentication Mode: None means all users will be granted access. It is not recommended.

    CORS: Enable this option.
