Integration infrastructure for enterprise products

Building an enterprise product or agent? Ampersand makes it easy to build reliable integrations with your customers’ systems of record like Salesforce, HubSpot, NetSuite, and many more. Ship deep, bidirectional integrations that adapt to each customer’s unique configuration, without the heavy lifting.

Read

Keep your customer’s data current with incremental reads, historical backfill, and on-demand reads.

Write

Create, update, or delete records, with per-field settings and defaults.

Subscribe

Real-time notifications when a record is created, updated, or deleted in your customer’s system.

Search

Find exactly the records you need by field value, with results returned right away.

Proxy

Call any endpoint directly. We handle auth and help with rate limits.

How Ampersand works

1. Define an integration

   Use an amp.yaml file to declare each integration: the system to connect to, the objects and fields to read or write, and the configuration options to expose to your customers. See the manifest reference.

   amp.yaml

   specVersion: 1.0.0
   integrations:
     - name: salesforce-accounts
       displayName: Salesforce Accounts
       provider: salesforce
       read:
         objects:
           - objectName: account
             destination: defaultWebhook
             schedule: "*/10 * * * *" # Every 10 minutes
             requiredFields:
               - fieldName: name
               # Each customer picks which of their fields holds this info
               - mapToName: renewalDate
                 mapToDisplayName: Renewal date
                 prompt: Which field holds the renewal date?
   
2. Let customers connect and configure

   Embed authentication and configuration in your product with prebuilt UI components, headless UI library, or API. Customers connect their own instance and choose field mappings and preferences, and Ampersand saves those choices in their installation.

3. Ampersand runs it

   A managed runtime tracks every customer’s configuration and makes the right API calls for each one. It handles authentication, scheduling, retries, rate limits, and non-standard provider error messages. You can either make direct API calls or have async results delivered to your destinations.

4. Monitor, adapt, and recover

   Inspect installations and operation logs, get notifications about connection issues, sync failures, and configuration changes, and watch for schema changes when fields are added, removed, or modified. Use these signals to operationalize your integrations by alerting your team or your customers when actions need to be taken.

Built for user-facing integrations

Ampersand handles multi-tenancy at scale. Say you have 400 customers on Salesforce. Every one of them has customized it to reflect how they run their business, with different custom objects, fields, permissions, and rules for how your product interacts with their data. Two very similar companies can store the same data in completely different places.

Ampersand separates the integration you build from each customer’s configuration. You define the schema and actions your application needs once, and each installation keeps track of the per-customer mappings. For example, you define renewalDate once, and each customer uses the embeddable UI library to map it to where they’re actually storing the renewal date in their Salesforce.

Customer	Where renewalDate lives
Customer A	Account.Renewal_Date__c
Customer B	Account.Contract_End__c
Customer C	Subscription__c.End_Date__c
…397 more	Each set by the customer during setup

Your application reads and writes renewalDate. Ampersand translates it to each customer’s field.
