# Custom source

> Send customer data from your own server to OpenScaffold: one HTTPS endpoint, one token.

Use a custom source when your customer data lives in a system we don't connect to: an in-house CRM, support desk or call system. Your server pushes records to OpenScaffold over HTTPS. You don't open a firewall port, you don't give us your credentials, and you choose exactly what leaves your network.

Everything you push is read like any other source: versioned, quoted word for word, and attributed to the person who wrote it.

## Connect

**1. Create the token**

A workspace admin opens **Settings › Sources › Custom source** and connects it. The token (`os_push_…`) is shown **once**. Store it as a secret, for example `OPENSCAFFOLD_PUSH_TOKEN`, never in code or logs.

**2. Hand the setup prompt to your coding agent**

The same screen shows a prompt with the full contract and your token. Paste it into Claude Code, Cursor or Codex on the repository that holds your customer data. The agent maps your data to the fields below, shows you the mapping, writes the sync job and runs the checks in [Verify](#verify) before backfilling.

**3. Backfill and schedule**

Push your history once, then run the job on a schedule (every 15 minutes works) or on your own change events.

## Push records

```bash theme={null}
curl -X POST https://app.openscaffold.ai/api/sources/push \
  -H "Authorization: Bearer $OPENSCAFFOLD_PUSH_TOKEN" \
  -H "Content-Type: application/json" \
  -d @records.json
```

The body holds 1 to 100 records:

```json records.json theme={null}
{
  "records": [
    {
      "id": "case-17",
      "container": { "id": "acct-acme", "name": "Acme" },
      "title": "SSO rollout",
      "url": "https://crm.example.com/cases/17",
      "occurredAt": "2026-11-01T09:00:00Z",
      "updatedAt": "2026-11-02T09:00:00Z",
      "customerDomains": ["acme.com"],
      "messages": [
        {
          "id": "m1",
          "author": { "name": "Dana Ruiz", "email": "dana@acme.com" },
          "text": "We need SCIM before go-live.",
          "at": "2026-11-01T09:00:00Z"
        },
        {
          "id": "m2",
          "author": { "name": "Sam Lee", "email": "sam@yourcompany.com" },
          "text": "Escalated to engineering.",
          "at": "2026-11-02T09:00:00Z",
          "internal": true
        }
      ]
    }
  ]
}
```

### Record fields

**id** `string` *required*

Your stable id for the record (1–200 characters). The same id is the same record; never reuse an id for a different record.

**container** `object` *required*

The collection the record belongs to, as `{ "id", "name" }`. Use one container per customer account. Each container appears under **Sources** and can be switched off there.

**occurredAt** `string` *required*

When the record started. ISO 8601 with `Z` or an offset.

**updatedAt** `string`

Your record's last-modified time. **Always send it.** A newer `updatedAt` makes a new version; an older one is ignored as stale. Without it, the newest message time decides.

**messages** `array` *required*

Every message, note or comment in the record, oldest first (up to 2,000).

**customerDomains** `string[]`

The customer's email domains (up to 20), when you know them. They decide which customer the record belongs to.

**title** `string`

Optional, up to 500 characters.

**url** `string`

Optional link back to the record in your system. `https` only. OpenScaffold never fetches it.

**deleted** `boolean`

`true`, with a newer `updatedAt`, when the record was deleted on your side. A record with no text is treated the same way.

### Message fields

**id** `string` *required*

Your stable message id. It lets OpenScaffold re-read only what changed when a record is edited.

**author** `object` *required*

`{ "name", "email" }`, with `email` when you know it. Your own team should use your company email so OpenScaffold knows they are on your side.

**text** `string` *required*

The exact words, up to 40,000 characters.

**at** `string` *required*

When it was written. ISO 8601 with `Z` or an offset.

**internal** `boolean`

`true` for notes your team wrote that the customer never saw. They are never read as the customer's words.

Leave out fields you don't have (`null` also works). Unknown fields are refused. No timestamp may be more than 5 minutes in the future.

## Responses

| Status | Body | What to do |
| - | - | - |
| `200` | `{ "stored", "unchanged", "stale", "switchedOff" }` | Done. `switchedOff` lists containers someone switched off; records sent there are dropped. |
| `400` | `{ "error" }` | The whole batch was refused. The error names the bad field. Fix it and resend. |
| `401` | `{ "error" }` | The token is wrong or the source was disconnected. Stop and check with your admin. |
| `429` | `{ "error" }`, `Retry-After` header | Over the hourly limit. Wait for `Retry-After`, then resend. |
| `503` | `{ "error" }` | Nothing was stored. Retry with backoff. |

**Resending is always safe.** The same record twice counts as `unchanged`; a changed record with a newer `updatedAt` becomes a new version, and what OpenScaffold knows about the customer is updated from it.

## Limits

| | |
| - | - |
| Records per request | 100 |
| Request size | under 4 MB |
| Messages per record | 2,000 |
| Characters per record | 400,000 |
| Characters per message | 40,000 |
| New record versions per hour | 5,000 (unchanged resends don't count) |
| Containers per source | 500 |

Push batches one request at a time.

## Verify

Before you backfill, check the job with three real records:

1. Push them. The response says `"stored": 3`.
2. Push the same three again. It says `"unchanged": 3`.
3. Change one message's text and send that record with a newer `updatedAt`. It says `"stored": 1`.
4. Open **Settings › Sources › Custom source** and check the records are there.

## Who sees it, and what you answer for

> [!WARNING]
>
> OpenScaffold trusts the authors your server sends, the same way it trusts who Slack or Linear says wrote a message. A message from `dana@acme.com` counts as the customer's own words. Only send authors your own system knows.

* **Everyone in the workspace sees it.** Every container your server sends is switched on when it first arrives and shared with the whole workspace.
* **Switching a container off** drops what is sent to it from then on. To stop the source completely, disconnect it.
* **Disconnecting** refuses the token at once. To use a new token, disconnect and connect again.
* **The token acts for the admin who created it.** It stops working if they are no longer a workspace admin.
* Every quote from a custom source cites its record, so you can always see where it came from.
* Keep the token out of logs. Log counts and record ids, never record text.
