Anyway to attach custom metadata to a user's payment

We need to add some metadata (key-values) to user’s payments. As an example, we’d like to send workspaceId and other key-value parameters along with a payment that user is creating.

I understand that there is a Subscriber attributes which offers capturing custom metadata on the user object, however what we need is to attach metadata to individual payments and not users.

Anyway to acheive this functionality with RevenueCat APIs?

This question was handled through our ticketing system, but posting the response here for visibility:

Unfortunately, passing metadata along with a purchase is not a use case currently supported by RevenueCat, but we’ve added this as a feature request. As a workaround, if you're keeping app user IDs in your own database, you could make a call to your backend to update a column for that particular user.

is there any update with this issue team? 

i also facing the same case, i need to send custom metadata when purchasing item, so i can receive the metadata on webhook

I’m also wanting this. I honestly would have thought this would be a key feature for RevenueCat as it adds a layer on the purchases not possible with native implementations. 

A very real example is gifting another user. The gifter makes an IAP to buy a gift, and all it would need is some meta data of the giftee id or likewise  to have this all processed on the server safely via the web hook. Right now, my implementation looks like I have to setup an intent on our server, which then has to be looked up via some fingerprinting when the revenue cat event comes to the server (whilst the client can (and does) send info, handling drop outs, or app crashes etc could mean lose of finalisation if not done properly, so I’m left with relying on receipt data only which is unsuitable)

Given the apple server events go via rev cat, surely you can just add an optional meta property to the purchase option or a new purchase method, even if it’s limited to 256 characters, we could at least encrypt id’s and attach.

Be interested though if you have any docs on handling such a common payment feature in an app (gifting / tipping etc) using RevCat ;-)

We need that feature asap !!

When will this feature be available. It is a basic requirement to send metadata along with a Subscription purchase and get the information back in Webhook.


Can someone from RC team respond to this?

Any update on this @sundeep? I need to attach some metadata to a product purchase / recurring purchase and retrieve that in my webhook on my server side. Looks like many revenuecat users need this as well

We are also looking for the exact same feature. We are decoupling purchases content from the SKU, and injecting some custom identifiers in a metadata field when a purchase starts would make our system robust.  

Same here. We have multiple teams where a user can buy “premium access” for the one he prefers. But my backend does not know what team the user selected when i handle the webhook coming vom rc.
