Facing error during creation of tickets through API's

We have integrated Jira Service Management & whatsapp using API’s. After integration, the instance worked fine and we have deployed the same in Production. Now, In production when the tickets are getting created, we are facing some error as below during ticket creation

Welcome to the Atlassian developer community @ChetanKrishnaSaiNaid,

There’s not a lot of context to go on. Next time, maybe have a look at our community guidelines on How To Ask A Good Question ❓. Meanwhile, the one clue we can see in the response is the HTTP status 429, which indicates too many API requests. You might start with the documentation on rate limiting.
