Create a New Named Credential

In this step, you create a Named Credential record that let's Salesforce access the SlapFive API.

Overview

This configuration:

• Stores the SlapFive API key securely using an External Credential

• Injects the API key into requests via a custom HTTP header

• Avoids hard-coding secrets in Apex, metadata, or logs

---

Step 1: Create an External Credential

1. In Salesforce Setup, navigate to External Credentials

2. Click New External Credential

Use the following values:

• Label: SlapFive External API

• Name: SlapFiveExternalAPI

• Authentication Protocol: Custom

Save the record.

---

Step 2: Create an External Credential Principal

1. From the External Credential record, create a new Principal

Use the following values:

• Parameter Name (Label): SlapFive API Key

• Sequence Number: 1

• Identity Type: Named Principal

1. Under Authentication Parameters, add a new parameter:

• Name: APIKey

• Value: Paste your SlapFive API key here

---

Step 3: Add a Custom Header to the External Credential

On the same External Credential, add a Custom Header:

• Header Name: api-authorization

• Value:

  {!$Credential.SlapFiveExternalAPI.APIKey}

• Sequence Number: 1

This injects the encrypted API key into every request at runtime.

Step 4: Create a Named Credential

1. In Salesforce Setup, navigate to Named Credentials

2. Click New Named Credential

Use the following values:

• Label: SlapFive API

• Name: SlapFive_API

• URL: enter the base URL of your SlapFive instance, which is: https://your_company_name.slapfive.com.

• External Credential: SlapFive External API

• Generate Authorization Header: Checked

• Allow Formulas in HTTP Header: Checked

• Allowed Namespaces for Callouts: SlapFiveInc

Save the record.

Step 5: Grant Access to the External Credential Principal

Users running SlapFive automations must be granted access to the External Credential Principal.

1. Open the target Profile or Permission Set

2. Find Enabled External Credential Principal Access

3. Add the Principal created in Step 2.
