The Lemma API is currently in beta. If you don’t see the option to generate an API key in your settings, reach out to the Lemma team at contact@getlemmalemma.com to be included in the API beta.

​
Generating an API key

  1. Log in to your Lemma dashboard
  2. Go to Settings
  3. Select the API keys section
  4. Select Generate new key
  5. Give the key a descriptive name (e.g., “Accounting integration”)
  6. Copy the key — it is only shown once
Store your API key securely. Do not share it or commit it to source control. If you believe a key has been compromised, revoke it immediately from the Settings page and generate a new one.

​
Using your API key

Include the key in the Authorization header of every request using the Bearer scheme: 
curl https://api.getlemma.com/v0/accounts \
  -H "Authorization: Bearer lm_key_your_api_key"

​
Key format

Lemma API keys are prefixed with lm_key_ so they are easy to identify. For example: 
lm_key_a1b2c3d4e5f6g7h8i9j0

​
Revoking a key

To revoke an API key:
  1. Go to Settings > API keys
  2. Find the key you want to revoke
  3. Select Revoke
Revoked keys stop working immediately. Any integration using that key will begin receiving 401 responses.
