Steps
Generate an API key from the Housecall Pro app store (requires the Pro to be on a MAX plan) or use OAuth2 if building a listed Integration Partner app.
POST to https://api.housecallpro.com/v1/jobs with an existing customer ID and address ID, plus line items (optionally referencing price-book UUIDs).
Set an Authorization bearer header and Content-Type application/json on every call.
Configure a webhook endpoint and signing secret in the account/app settings to receive customer, job, estimate, invoice, lead, and payment events.
Watch for HTTP 429 responses and read the RateLimit-Reset header (epoch time) to back off correctly.
Known gotchas
Job creation requires pre-existing customer/address records — there's no combined create-customer-and-job call.
API key access is gated to the MAX plan; lower plans can't self-serve API keys.
Webhook payload signature verification uses the account-specific signing secret, not the OAuth client secret used for partner apps.
