How to generate an API token
Generate a high-entropy API token, webhook secret, or session key. Free online generator plus secure-storage best practices.
A good API token is long, random, and secret. Here is how to generate one that cannot be guessed and how to handle it safely afterwards.
Generate high entropy
Use a cryptographically random generator — never a timestamp, a counter, or a "clever" pattern. Our token generator produces high-entropy strings suitable for API keys, webhook signing secrets, and opaque session tokens.
Store and rotate it safely
Keep tokens in a secret manager or environment variables, never in source control or client-side code. Scope each token to the minimum access it needs, rotate them periodically, and revoke immediately if one leaks.
Step by step
Open the token generator and choose a length of at least 32 characters.
Generate and copy the token.
Store it in a secret manager or environment variable — never in git.
Send it as an Authorization: Bearer header, scope it narrowly, and rotate on a schedule.
