Quickstart

You can be live in three steps.

1. Get an API key#

Sign in, then visit /settings/developer. Each key is scoped to a single agent.

2. Run your first calculation#

curl -X POST https://app.mortgagemeter.ca/api/v1/calculate/maximum-mortgage \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "inputs": { "grossAnnualIncome": 120000, "downPayment": 100000, "debts": [], "rentalIncome": { "rentalIncome": 0 }, "annualPropertyTax": 4800, "monthlyHeating": 100, "monthlyCondoFees": 0, "contractRate": 5.39, "amortYears": 25, "gdsCap": 0.39, "tdsCap": 0.44 } }'

3. Subscribe to webhooks#

Configure a webhook endpoint in /settings/developer. MortgageMeter POSTs everylead_received, sheet_viewed, and verified_calc_used event to your URL — signed with HMAC-SHA-256 per Webhooks.
