# createCallingFunction

> v0.20.5

> **createCallingFunction**(`config`, `rulesEngineComponentContract`, `policyId`, `callingFunction`, `name`, `encodedValues`, `confirmationCount`): `Promise`\<\{ `functionId`: `number`; `transactionHash`: `` `0x${string}` ``; }>

Defined in: [src/modules/calling-functions.ts:53](https://github.com/Forte-Service-Company-Ltd/forte-rules-engine-sdk/blob/40cc8388cecd8ee445b00b9df2b681cff8552ece/src/modules/calling-functions.ts#L53)

Creates a Calling Function in the rules engine component contract.

This function parses the provided calling function, maps its arguments to their respective
types, and interacts with the smart contract to create the calling function. If the contract
interaction fails, it retries with a delay until successful.

## Parameters

| Parameter                              | Type                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          | Description                                                                                        |

## Returns

`Promise`\<\{ `functionId`: `number`; `transactionHash`: `` `0x${string}` ``; }>

A promise that resolves to the result of the contract interaction, or -1 if unsuccessful.

## Throws

Will retry indefinitely on contract interaction failure, with a delay between attempts.
