If your organization has custom fields associated with your patient roster, you can update and retrieve these values through this API.
When retreiving a contact, you will be given two related fields:
- custom_field_names
- custom_field_values
The custom_field_names field maps the global identifier of your custom fields to their human-readable name. This field is read-only and is for informational purposes only.
The custom_field_values field maps these same field IDs to the value contained for each contact that you are interacting with. This field can be written to, in case you need to update a custom field.
For example, consider Jane Doe:
{
"url": "https://api.oncallhealth.ca/contacts/1234/",
"name": "Jane Doe",
"email": "[email protected]",
"phone": "2125551542",
"sex": "Unknown",
"date_of_birth": "1970-01-01",
"custom_field_names": {
452: "EMR id",
664: "Has submitted forms?"
},
"custom_field_values": {
452: "Ax1A2",
664: true
},
"appointments": "https://api.oncallhealth.ca/contacts/1234/appointments/",
}
We can see that Jane Doe has two custom fields: "EMR id". which has ID 452, and "Has submitted forms?" which has ID 664. By matching the IDs with the custom_field_values field, we can see that Jane Doe has an "EMR id" value of "Ax1A2" and "Has submitted forms?" is true.
To update the value of a custom field, simply PATCH the contact with the fields you intend to change. For example, if we PATCH https://api.oncallhealth.ca/contacts/1234/ with the following body:
"custom_field_values": {
452: "Mx978A",
}
We will change the EMR id of Jane Doe to be "Mx978A".
