My Mautic version is: 4.4.7  
My PHP version is: 8.0.30  
My Database type and version is: pdo\_mysql and 8.0.36

**Your problem**  
My problem is: I have a PHP script where it fetches the contacts from the third party API , now whenever it runs it should create a contact or update an existing contact in the segment. Can anyone please help me on this process.

These errors are showing in the log:

The Mautic Dev documentation is your friend here:  
[https://developer.mautic.org/#create-contact](https://developer.mautic.org/#create-contact)

1. First enable access (Basic Auth) in Mautic.
2. Add a user for the API with required access rights.
3. Implement the calls: You need to check first, if contact already exists, if not add a new one.

Not sure what you mean related to the assignment of the contact to a segment - that would be the way to go: [Mautic Developer Documentation](https://developer.mautic.org/#add-contact-to-a-segment)
