Integromat to whmcs auth issue

[Rani]

hello community

i have an issue configuring http access from integromat (make) to whmcs.

i have followed all documentation for api access and using all the necessary arguments using identifier/secret and access key.

but i get a authentication failed again and again.

 

i have attached screenshot for the config template i use.

same credentials in zapier works fine, so there is not real auth issue.

 

if some one came across something like this, i would really appreciate your help.

 

thanks

Rani
