How can we give permission to Approver to use Identity Manager 7.0 REST API to accept a request?

Question

We are using the IdM 7 REST API to obtain pending requests for a given approver (using the Approver's credentials). However, we have a permission issue when trying to update a given request to the Approver using the makeDecision method. We can only use the API and the method to modify the request when signing with an admin account.

If you are using a normal user, role-based or not is irrelevant, the user needs to have a program function assigned called Common_StartCustomizerMethods . 
 These program function can be assigned to permission groups and you just need to ensure, that your logged in user is a member of a permission group with that program function assigned. 
 For role-based groups that means that your person has to assigned to an application role, where a permission group is assigned that grants the person access to the program function mentioned.
