Contact ID VS Identifier Number
Overview
In WooSender, the Contact ID is a unique identifier assigned to each contact in the system. However, depending on the API endpoint you use, this identifier may appear under different field names.
Understanding this difference is important when integrating or automating workflows.
1. Using the “Find Contact” API
When you use the Find Contact API, the response includes a field explicitly labeled:
contactId → This is the unique Contact ID
Example Response:
{
"contactId": "123456789",
"name": "John Doe",
"email": "john@example.com"
}
Key Point:
The field is clearly named contactId
This is the standard identifier you should store and reuse
2. Using the “Create Contact” API
When you create a new contact using the Create Contact API, the Contact ID is not labeled as contactId.
Instead, it appears as:
identifierNumber
Example Response:
{
"identifierNumber": "123456789",
"name": "John Doe",
"email": "john@example.com"
}
Key Point:
identifierNumber = Contact ID
It represents the same value as contactId, just under a different field name
3. Using the “Create Appointment” API
Similarly, when creating an appointment, the contact reference is returned as:
identifierNumber
Example:
{
"appointmentId": "987654321",
"identifierNumber": "123456789"
}
Key Point:
Again, identifierNumber is the Contact ID
This links the appointment to the contact
4. Summary Mapping
API Endpoint | Field Name | Meaning |
Find Contact | contactId | Contact ID |
Create Contact | identifierNumber | Contact ID |
Create Appointment | identifierNumber | Contact ID |
5. Best Practice
Always treat contactId and identifierNumber as the same value
When building integrations:
Normalize the field to a single internal name (e.g., contact_id)
Store it consistently regardless of the source endpoint
6. Recommended Approach in Automation (e.g., Zapier)
If using Find Contact → map contactId
If using Create Contact / Appointment → map identifierNumber
Store the value in a single variable (e.g., contact_id)
Use that variable in downstream steps
