The Mambu integration is delivered as several outbound (synchronous) runtime connectors that call the Mambu API v2. Each connector is configured in its own `values.yaml` file. For setup steps, see [Get started](/connectors/core-banking/mambu/get-started). | Connector | Property file | Purpose | | :--------------------------------------- | :--------------------------------------------- | :----------------------------- | | `gc-mambu-deposit-connector` | `deposit-v0.values.yaml` | Deposit account operations | | `gc-mambu-deposit-transaction-connector` | `deposit-transactions-v0.values.yaml` | Deposit transaction operations | | `gc-mambu-loan-connector` | `loan-v0.values.yaml` | Loan account operations | | `gc-mambu-loan-transaction-connector` | `loan-transactions-v0.values.yaml` | Loan transaction operations | | `gc-mambu-payment-connector` | `payment-v0.values.yaml` | Payment operations | | `gc-mambu-party-connector` | `party-v0.values.yaml`, `party-v2.values.yaml` | Party management operations | ## Configuration properties ### Values to obtain from Mambu Obtain the following value from Mambu and set it in `values.yaml`. This value is environment-specific, so it has no default. | Property | Description | | :-------------- | :--------------------------------------------- | | `mambu.baseUrl` | Target API endpoint for the Mambu environment. | ### Common properties Set these properties in `values.yaml`. They apply across all Mambu connectors. Product ID mappings set here are inherited by the deposit and party connectors. | Property | Description | Default | | :------------------------------------- | :------------------------------------------------------------- | :-------------------------------------- | | `existingSecretName` | Reference to the SOPS secret that holds the Mambu credentials. | `mambu` | | `http.client.connect.timeout` | HTTP connect timeout, in milliseconds. | `5000` | | `http.client.request.timeout` | HTTP request timeout, in milliseconds. | `10000` | | `http.client.socket.timeout` | HTTP socket timeout, in milliseconds. | `5000` | | `http.client.connection.max.per.route` | Maximum HTTP connections per route. | `100` | | `http.client.connection.max.total` | Maximum total HTTP connections. | `200` | | `redelivery.backOffMultiplier` | Backoff multiplier for redelivery attempts. | `2` | | `redelivery.delay` | Initial delay between redelivery attempts, in milliseconds. | `200` | | `redelivery.maximumRetries` | Maximum number of redelivery attempts. | `3` | | `retryFlag` | Enable automatic request retries on connection failure. | `false` | | `errorTemplate` | Transformation template used to map core error responses. | `transform-mambu-error-details-v2.json` | | `thread.profile.core.pool.size` | Core thread pool size. | `20` (`10` for the deposit connector) | | `thread.profile.max.pool.size` | Maximum thread pool size. | `20` | The following product ID mapping patterns translate between Grand Central product types and Mambu product IDs. | Pattern | Description | | :------------------------------------ | :--------------------------------------------------------------- | | `product....id` | Forward mapping: Grand Central product type to Mambu product ID. | | `` | Reverse mapping: Mambu product ID to Grand Central product type. | The product ID mapping values are environment-specific. Contact your Mambu administrator to obtain the full list of product IDs for your tenant. ### gc-mambu-party-connector and gc-mambu-deposit-connector The party and deposit connectors hold basic configuration. They inherit the product ID mappings from the common `values.yaml`. No additional connector-specific properties are documented in [Get started](/connectors/core-banking/mambu/get-started). ### gc-mambu-deposit-transaction-connector Set this property in `deposit-transactions-v0.values.yaml`, in addition to the common properties. | Property | Description | Default | | :------------------- | :------------------------------------------------------- | :------ | | `isMockedDataNeeded` | Return mocked transaction data instead of calling Mambu. | `false` | ### gc-mambu-loan-connector Set these properties in `loan-v0.values.yaml`, in addition to the common properties. | Property | Description | Default | | :------------------------------------ | :--------------------------------------------------------------- | :------ | | `product....id` | Forward mapping: Grand Central product type to Mambu product ID. | N/A | | `` | Reverse mapping: Mambu product ID to Grand Central product type. | N/A | | `timeZone` | Optional. Time zone applied to loan operations. | `CET` | | `` | Optional. Maps a Mambu error code to a Grand Central error code. | N/A | ### gc-mambu-loan-transaction-connector Set these properties in `loan-transactions-v0.values.yaml`, in addition to the common properties. | Property | Description | Default | | :------------------- | :--------------------------------------------------------------- | :------ | | `isMockedDataNeeded` | Return mocked transaction data instead of calling Mambu. | `false` | | `isLoanExistCheck` | Verify that the loan exists before retrieving transactions. | `true` | | `` | Optional. Maps a Mambu error code to a Grand Central error code. | N/A | ### gc-mambu-payment-connector Set this property in `payment-v0.values.yaml`. The payment connector uses the common properties and defines the following connector-specific error-code overrides. | Property | Description | Default | | :---------------- | :---------------------------------------------------------------------------------------------- | :------ | | `` | Maps a Mambu error code to a Grand Central status code, for example `428=GC401` or `401=GC409`. | N/A | ## SOPS secrets The connectors use Basic authentication with credentials stored in a SOPS secret, referenced by the `existingSecretName` property. Obtain the following credentials from Mambu. For details, see [Get started](/connectors/core-banking/mambu/get-started). | Credential | Description | | :--------------- | :--------------------------------- | | `mambu-user-id` | Username for Basic authentication. | | `mambu-password` | Password for Basic authentication. | ## Supported operations The Mambu connectors expose the Grand Central Unified API. For the operation-to-endpoint tables per domain (deposit, deposit transactions, loan, loan transactions, payment, party), see [Overview](/connectors/core-banking/mambu/overview). For the full contract, see the [unified API specifications](/connectors/reference/unified-api-specifications). ## Events These connectors are synchronous and do not publish or consume events. ## Error mapping The connector maps Mambu error codes to Grand Central status codes. For the full list, see [Error codes](/connectors/reference/error-codes). You can configure connector-specific overrides as core-to-Grand Central code pairs in a connector's `values.yaml`; the payment connector ships with overrides for several Mambu error codes (see [gc-mambu-payment-connector](#gc-mambu-payment-connector)). The loan and loan transaction connectors also accept overrides through the `` property. ## Dependencies * Mambu API v2 (outbound), reachable at `mambu.baseUrl`. * The shared `mambu-connector-sdk` library.
