How do I authenticate a user to obtain a merchant ID?

Shopify Discussion

Topic summary

Main issue: How to authenticate to receive a store’s merchant ID (a backend identifier for a Shopify account).

Key guidance:

  • Authentication is completed by logging into the specific store/account before entering live support queues; this login serves as verification.
  • If you reach support without logging in, an agent will provide a link during the interaction so you can log in and authenticate on the spot.
  • After authentication, support can access backend information and provide your merchant ID.

Resources mentioned:

  • A direct link to contact live support was provided.
  • A tool was shared to confirm you are referencing the correct account, useful if you manage multiple accounts.

Outcome and status:

  • Clear process established: log in to authenticate, then request the merchant ID from support.
  • No disagreements noted; the question appears resolved with actionable next steps.

Notes on terms:

  • “Merchant ID” refers to the store’s unique backend identifier.
  • “Authentication” means verifying account ownership by logging into the store.

Hi @Shopify_77 ,

I was looking for a merchant ID in the portal and I got to know for getting a merchant ID you must be able to authenticate us first. So, I just want to know what all information you required to authenticate a User?

Thank you

Hi there, @Chris_Battaglin !

Welcome to the Community! Definitely a great place to gather some input regarding anything about the platform!

With regards to your inquiry however, authentication tends to happen before even reaching our live support team. You simply need to log on to the store/account that you want to discuss before going into the live queues and this will act as your authentication.

If you come in without logging into your store however, one of our agents will provide further instructions to manually authenticate yourself during the interaction. You will simply need to log into your account using the link provided and this will act as your authentication.

Once you are, our team will be able to open up back end information and provide those details for you such as your merchant ID.

In order to reach our live team, please utilize this link. I have also attached this tool from us to ensure that you are referring to the correct account as it can be a bit confusing at times, especially to those with multiple accounts on the platform.

Definitely let me know how this works out for you.
