SDKs

Eleven official SDKs speak the same /v1 contract with identical group structure (link, institutions, items, accounts, transactions, identity, income, assets, investments, liabilities, recurring, categories, ai, sandbox) plus a webhook verification helper. All default to https://api.feelconnect.dev/v1, 30-second timeouts, and no implicit retries.

let feelconnect = FeelConnectClient(
    apiKey: ProcessInfo.processInfo.environment["FEELCONNECT_API_KEY"]!
