Does Data API retry async requests?

If the initial requests fail with a 5XX error we will continue to retry the request for the lifetime of the access token.

Example:

Request to /accounts endpoint fails with 504, provider_timeout. In this case, the bank is experiencing a slower than usual response time. Most likely if we keep trying whilst the access token is still valid the bank will return accounts.
