usage

Browsers	🚧 @octokit/webhooks-methods is not meant to be used in browsers. The webhook secret is a sensitive credential that must not be exposed to users. Load @octokit/webhooks-methods directly from esm.sh <script type="module"> import { sign, verify, verifyWithFallback, } from "https://esm.sh/@octokit/webhooks-methods"; </script>
Node	Install with npm install @octokit/core @octokit/webhooks-methods import { sign, verify, verifyWithFallback } from "@octokit/webhooks-methods";

await sign("mysecret", eventPayloadString);
// resolves with a string like "sha256=4864d2759938a15468b5df9ade20bf161da9b4f737ea61794142f3484236bda3"

await verify("mysecret", eventPayloadString, "sha256=486d27...");
// resolves with true or false

await verifyWithFallback("mysecret", eventPayloadString, "sha256=486d27...", ["oldsecret", ...]);
// resolves with true or false

Methods

sign()

await sign(secret, eventPayloadString);

secret (String)	Required. Secret as configured in GitHub Settings.
eventPayloadString (String)	Required. Webhook request payload as received from GitHub. If you have only access to an already parsed object, stringify it with JSON.stringify(payload)

Resolves with a signature string. Throws an error if an argument is missing.

verify()

await verify(secret, eventPayloadString, signature);

secret (String)	Required. Secret as configured in GitHub Settings.
eventPayloadString (String)	Required. Webhook request payload as received from GitHub. If you have only access to an already parsed object, stringify it with JSON.stringify(payload)
signature (String)	Required. Signature string as calculated by sign().

Resolves with true or false. Throws error if an argument is missing.

verifyWithFallback()

await verifyWithFallback(
  secret,
  eventPayloadString,
  signature,
  additionalSecrets,
);

secret (String)	Required. Secret as configured in GitHub Settings.
eventPayloadString (String)	Required. Webhook request payload as received from GitHub. If you have only access to an already parsed object, stringify it with JSON.stringify(payload)
signature (String)	Required. Signature string as calculated by sign().
additionalSecrets (Array of String)	If given, each additional secret will be tried in turn.

This is a thin wrapper around verify() that is intended to ease callers' support for key rotation. Resolves with true or false. Throws error if a required argument is missing.
