Hi Smriti,
Thank you for posting your concern.
In order to upload customer match in your account by either using UI or API, you will need to meet the requirements discussed on this
document first. Then, after completing the requirements, you will need to reach out to your account manager or Google representative in order to allowlist your account for uploading customer match.
You may refer to this
blog post to read more information about customer match requirements. Let me know if you have further questions.
Regards,
