What’s New at Shopify?

When connecting Flow to external APIs, you often need to hash API keys, customer data, or other sensitive information for security.

You can now hash data directly in your Flow workflows using the same hashing functions in Liquid that Shopify themes uses, including: sha1, sha256, md5, hmac_sha1, and hmac_sha256. Simply add the filter to any variable in your workflow. For hmac filters, include an authentication code as a parameter.

Examples:
* Hash a customer email: {{ customer.defaultEmailAddress | sha1 }}
* Hash a customer email using hmac_sha256: {{ customer.defaultEmailAddress | hmac_sha256: "your-secret-key" }}

For complete filter documentation, check the Liquid reference for each filter. Questions? Visit the Shopify Community.
