I'm having doubts in the process of creating a connection with an api.
I have already created the Integration System> Integration> Add New Integration with access to everything.
Via Postman I configured the OAuth 1.0 type authorization and when doing a GET https://myserver.com/rest/V1/modules give me the answer
"message": "Consumer is not authorized to access% resources",
"resources": "Magento_Backend :: admin"
If you allow Allow Anonymous Guest Access I can already access it.
Can you help me
How is the authentication made?
