Terraform Environment Variables

Every provider argument can be supplied via an environment variable. Using environment variables keeps secrets out of your .tf files and Terraform state.

Variable	Provider argument	Required	Description
WEBHOOKR_API_URL	api_url	Yes	Webhookr API base URL, e.g. https://api.webhookr.tech.
WEBHOOKR_API_TOKEN	api_token	Conditional	API token (whk_…). Mutually exclusive with the Firebase variables.
WEBHOOKR_FIREBASE_API_KEY	firebase_api_key	Conditional	Firebase Web API key.
WEBHOOKR_SERVICE_ACCOUNT_EMAIL	service_account_email	Conditional	Service account email (name@project.iam.gserviceaccount.com).
WEBHOOKR_SERVICE_ACCOUNT_KEY	service_account_key	Conditional	Service account RSA private key, in PEM format.

Authentication rules

• Provide either WEBHOOKR_API_TOKEN or the three WEBHOOKR_FIREBASE_* / service account variables — never both.
• When WEBHOOKR_API_TOKEN is set, the Firebase variables are ignored, even if exported. This prevents a false Conflicting authentication error in shared environments.
• The three Firebase variables are required together.

Example

export WEBHOOKR_API_URL="https://api.webhookr.tech"
export WEBHOOKR_API_TOKEN="whk_xxxxxxxxxxxxxxxxxxxxxxxx"
