Enter Phone Number, Show Contact Details with API?

Question

There is a system where we answer calls from our members. We save all of these calls by creating contact information on CiviCRM and create the conversation in an activity.

People answering the calls create a contact by entering different information on the same number. I don't want that to happen. So, Can she create an API to enter a phone number and output a name?

Answer 1

You can, certainly - but it sounds like what you really want to do is set the Supervised Dedupe rule to dedupe on phone number. That way, when someone enters a new contact, when they try to save it, it will recognize the person as a duplicate.

Answer 2

Can she create an API to enter a phone number and output a name

If I understand the question right, the API is already available. If you simply need an api that provides the name based on phone number, you can use -

$contact = civicrm_api3('Phone', 'get', [
  'sequential' => 1,
  'return' => ["contact_id"],
  'is_primary' => 1,
  'phone_numeric' => <numeric value of the phone number>, // 12345678 if phone number is 12-345-678
  'api.Contact.get' => ['id' => "\$value.contact_id"],
]);

$contact has all the information related to contact. You can try more such API combination from the API explorer
