Shopify GraphQL customerSmsMarketingConsentUpdate mutation not working

Retired Boards Appdev Customers Discounts And Orders

Topic summary

A developer is experiencing an issue with Shopify’s GraphQL customerSmsMarketingConsentUpdate mutation, though the examples provided show the customerEmailMarketingConsentUpdate mutation instead.

What’s Working:

  • The email marketing consent mutation executes successfully
  • Returns proper response with marketingState: UNSUBSCRIBED
  • No user errors are reported
  • Customer query by ID retrieves consent data correctly

The Problem:

  • Despite the title mentioning SMS consent updates, only email consent mutation code is shown
  • The post contains garbled/reversed text in several sections, making parts difficult to parse
  • No error messages or specific failure descriptions are provided

Status: The issue remains unresolved with no responses or solutions posted. It’s unclear whether the SMS mutation fails silently, returns errors, or if the wrong mutation was shared in the example.
