Session expired or invalid on using access token

I have created a connected app in which I have selected the OAuth Scopes "Access and manage your data (api)" and "Full access (full)" through the consumer key and consumer secret that was available in the new connected app, I have generated an access token.

But when I send a new put request to the RestResource that I have created in my sandbox instance, with the header key as "Authorization" and value as "Bearer my_access_token" I am receiving the below error.

[
  {
    "message": "Session expired or invalid",
    "errorCode": "INVALID_SESSION_ID"
  }
]

the url to which I am sending the request looks like this

https://my_instance_url/services/apexrest/CustomerAccountSync

I tried changing the way I send access token by adding "OAuth" instead of "Bearer" in the header. But I am still receiving the same error response.

Can anyone please let me know why this is happening? I am using "Insomnia" to make the API call.

Solution

  • And you're sure you're sending to different endpoint? login call can go against generic login.salesforce.com or test.salesforce.com. But all requests after login need to use the instance_url that came back in the response, just like you have to use access_token from now on.

    It'll be in https://mydomain.my.salesforce.com format so you need https://mydomain.my.salesforce.com.salesforce.com/services/data/v50.0/query?q=SELECT Id FROM Account
