Campaign messages

Hello,

I need to send campaign messages to around 90k users. Are there any API limits per user? If so, what is the limit?

Can I send the messages in batch via Webex APIs or does it have to be one by one?

Thanks

@sharatb if you are talking about the Messages API then you will need to deal with potential rate limiting. Best way to deal with it is to implement a logic for handling 429 responses. We have a good blog post for that here https://developer.webex.com/blog/rate-limiting-and-the-webex-api and further resources here https://developer.webex.com/messaging/docs/basics#rate-limiting .
