Rest Connector 429 Error - Too Many requests

[nayanqlik]

Hi

I have a connection to a URL using a REST connector. The connection has succeeded however when I save or when i request data i get a 429 Error.  (see below). The issue is that we have not done a request too many times. 

The is another app called POSTMAN and request from this app works perfectly fine.

Please can you assist as to why I'm having this error with a REST Connector.

Kind regards

Nayan
