Shopify Business Central Connector - Don't get an access token

Hi @Emile Peels | Flexx Menswear

Thank you for posting your question in the Microsoft Q&A forum.    

Regarding your issue, I understand how frustrating it can be when everything appears to be configured correctly, yet the access token is still not returned to Business Central despite trying multiple troubleshooting steps. Since this issue relates to Dynamics 365 Business Central, it would be best to raise a support ticket with Dynamics 365 Business Central support for further assistance.

Here are a few steps you can try: 

1. Raise a support request via Business Central 

• If you have admin access, you can raise a ticket following the steps here: How to raise a support ticket for Business Central 

2. Contact your Business Central partner/reseller 

• If you don’t see the option to create a support request, please contact your Dynamics 365 Business Central partner or reseller and ask them to raise a ticket on your behalf. Business Central support cases are typically escalated through the partner channel, especially for connector‑level or backend issues. 
• For more details, please refer to: Escalate support issues to Microsoft - Business Central 

Additionally, since this issue relates specifically to Dynamics 365 Business Central, if you run into any problems in the future, I’d recommend posting your question directly in the Dynamics forum as that community is more focused on Dynamics‑related issues and often has experts who are familiar with connector and integration scenarios like this. 

Once again, I apologize for redirecting you to a different community as the members of the posted category focus on users with Microsoft 365 concern and have limited knowledge about Dynamic, so to get a quick and better assistance, we redirect you in the correct way.   

Thank you for your patience and understanding, if you have any other questions or need further assistance, feel free to ask.

The access token is only set in Business Central when Shopify successfully returns it to the connector. Use the following checks and recovery steps that are documented for the Shopify connector:

1. Verify the shop URL and enablement
   • On the Shopify Shop Card, confirm that Shopify Admin URL is in the required format https://{shop}.myshopify.com/ (the connector can convert from https://admin.shopify.com/store/{shop} automatically).
   • Turn on the Enabled toggle and accept the terms. This should open a browser page saying Waiting for a response - do not close this page while Shopify sends back the token.
2. Allow pop‑ups and cookies in the browser
   • If the Waiting for a response page is blocked or closed (for example by a pop‑up blocker or cookie restrictions), the token is never returned and Has AccessKey stays off.
   • Ensure the browser allows pop‑ups and cookies for Business Central and Shopify, then repeat the access request.
3. Request the access token again
   • In Business Central, go to Shopify shops → open the shop → choose Request Access.
   • If prompted, sign in to Shopify, review the privacy terms and permissions, and choose Install App.
   • After a successful flow, the Has AccessKey toggle on the shop card is turned on.
4. Check for known issues and permission problems
   • If errors such as Invalid API key or access token, Access denied for FIELD field, or The application scope is changed, please request a new access token occur, request a new token as above; newer connector versions may require additional scopes.
   • If Shopify shows Your account does not have permission to grant the requested access for this app or You need permissions to update Dynamics 365 Business Central, the Shopify user installing the app must have rights to manage and install apps. Install as the store owner or adjust App permission in Shopify admin → Users and permissions and then request access again.
5. If using a sandbox/non‑production Business Central
   • Open Extension Management → select Shopify Connector → Configure.
   • Ensure Allow HTTPClient Requests is enabled; otherwise the connector cannot complete the token exchange.
6. If the token needs to be rotated or the app was reinstalled multiple times
   • In Shopify Admin → Apps, delete the Dynamics 365 Business Central app.
   • Then in Business Central, on Shopify shops, open the shop and run Request Access again and complete the install flow.

After these steps, when the OAuth flow completes successfully, the Has AccessKey field should no longer be greyed out and will be turned on.
