We use Klaviyo's 2024-02-15 version of events-api to synchronize customer information. Our system shows that the phone number returned by you is not standardized. Can you explain to us how you verify the phone number?

Hey
Thanks for posting in the community.
Can I check if the message you’ve shared is from the non-Klaviyo system?
It looks like this has been an issue for some time - can you confirm if the following is the same problem you’re experiencing?
Thanks,
Ross
Hi
Let me know if the thread that ross_hopkins posted above answers your questions. To summarize, when making an API call to Klaviyo, the phone number must be in a valid format for the call to succeed. A valid phone number format would be “+15005550006” for instance. Does this answer your question? If not, let us know!
