Facebook Custom Event Names Power Script

Replace the name of any standard Facebook event with a custom event name of your choice - for example report your purchases as "ETSC1" instead of the standard "Purchase" event.

This Power Script exists primarily for advertisers in restricted categories (health & wellness, financial services, and others) whose standard events Meta blocks from campaign optimization: a confirmed custom event with a neutral name remains usable for optimization, custom conversions and value optimization. Leave any event unmapped and it keeps working exactly as before.

The custom name is applied to the browser pixel and the Conversions API automatically, with event deduplication preserved - value, currency and product data stay unchanged. After the first fire, confirm the new event in Meta Events Manager (Datasets → Settings → Data restrictions) and re-select it in your ad sets.
