hi

[lucid swan]

I'm not familiar with building lambda functions, but generally speaking you'll need to preserve the raw request body in order to pass in to signature verification

Are you able to access this on the request to the lambda?

[grand jolt]

i am hosting netlify functions

[lucid swan]

Similar for a node/express endpoints, say: https://github.com/stripe-samples/accept-a-payment/blob/main/custom-payment-flow/server/node/server.js#L18-L28

I don't think that's possible based on this netlify post i was reading:
https://answers.netlify.com/t/how-do-i-get-raw-body-in-my-lambda/5439/14

[grand jolt]

i can not use express in my lambda function

[lucid swan]

But i'd suggest reaching out to them for guidance to see if thats changed

If you can't get the raw body, you'll be unable to verify the signature

[lucid swan]

i know, i meant as an example of access the raw request body before parsing, not sure how lambdas do this

[grand jolt]

ok

thank you

😦 I am trying this for 4 days

If you find an answer, please do share. I'd love to know if/how it can be done.

but if i am pressing the green button many times it works as like i would use the raw body which is very strange

And also i am getting 2 diffrent errors. in my webhook terminal in vscode i am getting "{\"error\":\"webhook error Unable to extract timestamp and signatures from header\"}", and on stripe website when i am checking the same request i see "{\"error\":\"webhook error No signatures found matching the expected signature for payload. Are you passing the raw request body you received from Stripe?"}"

If you have access to the AWS config you might be able to set up something like this:

But not sure if that's possibly via Netlify

[grand jolt]

i think it is not possible
