# List a template's versions

`GET /v1/whatsapp/templates/{template_ref}/versions`

Returns the template's versions, newest first. Each names the languages it holds and what became of them; content is not here, since a page of versions would carry a copy of every language in every one of them. Read a single version for its content.

## Code samples

### TypeScript

```ts
for await (const version of bird.whatsapp.templates.versions.list("bird_otp")) {
  console.log(version.id, version.version_number);
}
```

### Python

```py
for version in client.whatsapp.templates.versions.list("bird_otp"):
    print(version.id, version.version_number)
```

### Go

```go
for version, err := range client.Whatsapp.Templates.Versions.List(context.Background(), "bird_otp", bird.WhatsappTemplatesVersionsListParams{}) {
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(version.Id, len(version.Languages))
}
```

### PHP

```php
foreach ($bird->whatsapp->templates->versions->list('bird_otp') as $version) {
    echo $version->getId(), ' ', $version->getVersionNumber(), "\n";
}
```

### CLI

```sh
bird whatsapp templates versions list <template-ref>
```

### cURL

```sh
curl -X GET "https://us1.platform.bird.com/v1/whatsapp/templates/{template_ref}/versions" \
  -H "Authorization: Bearer $TOKEN" \
  --url-query "limit=25"
```

## Path parameters

- `template_ref` (string): Template ID (`wat_` prefix) or slug. A value that parses as a valid ID resolves by ID; any other value resolves as a slug.

## Query parameters

- `limit` (integer): Maximum number of items to return per page.
- `starting_after` (string): Cursor from the `next_cursor` field of a previous list response. Returns items immediately after the cursor position in the current sort order.
- `ending_before` (string): Cursor from the `prev_cursor` or `refresh_cursor` field of a previous list response. Returns items immediately before the cursor position in the current sort order. `prev_cursor` returns the preceding page. `refresh_cursor` anchors at the first row of that response, which on a newest-first sort is how to fetch the items that have appeared since.

## Response body

- `data` (array of object, required): Page of the template's versions, newest first.
- `data.id` (string, required): Stable Bird identifier for the version.
- `data.template_id` (string, required): The template this version belongs to.
- `data.version_number` (nullable integer): The version's sequence number, assigned when it is submitted. Null on a draft, which has not been submitted and has no place in the sequence yet.
- `data.submitted_at` (nullable string, required): When this version was submitted to Meta. Null on a draft, which has not been submitted, and null for a built-in template's version, which Bird ships already approved rather than submitting on your behalf.
- `data.languages` (object, required): What this version's submission did with each language it holds, keyed by BCP-47 language tag. Content is not here: read the version for that.
- `data.created_at` (nullable string, required): When the version was opened. Null for a built-in template's version, which Bird ships rather than stores.
- `data.next` (array of object)

  What to do next with this version, given whether it has been submitted. Present on
  reads that compute it: an empty list means there is nothing to do, and the field is
  absent entirely on responses that do not report next actions.

  A version with no `version_number` is the open draft, and routes to writing its
  languages and checking it. One that carries a number is frozen, so it routes to
  reading the verdicts it holds. `submitted_at` does not separate the two, because
  it is also null on a built-in template's version.
- `data.next.kind` (string, required)

  What you do about this step.

  - `operation`: call the operation named in `operation`, then
    read again.
  - `external`: act somewhere this API does not reach, then read
    again.
  - `wait`: nothing is asked of you, so read again later.
  - `terminal`: nothing you do resolves this, so stop retrying.

  Tolerate a value you do not recognize: show the `description` and
  offer no action.

  Possible values (may grow over time): `operation`, `external`, `wait`, `terminal`
- `data.next.description` (string, required): A short, human-readable label for the step, suitable for display.
- `data.next.operation` (string): The operationId to call. Present only when `kind` is `operation`. The operation's own schema says how to call it; this says only which one, and what to address it with.
- `data.next.params` (object): The parameters that address the operation, by name: `{"sender_id": "…"}` for an operation on `/v1/sms/senders/{sender_id}/requirements`. A parameter the operation takes in its query string is given the same way, so an operation addressed as `?subject_id=` carries `{"subject_id": "…"}`. Every parameter the call needs is here, whether its value came from the thing you were acting on or is fixed for this step, so you can make the call from this object alone. Present only when `kind` is `operation` and the operation names a subject. A request body, when the operation takes one, is described by the operation's own schema and never appears here.
- `data.next.url` (string): A URL to open. Present only when `kind` is `external`, and only when the step has one. An external step whose `description` says to go and do something with no URL to open is normal.
- `next_cursor` (nullable string, required): Cursor for the next page. Pass back as `starting_after` to advance forward. `null` when no next page exists.
- `prev_cursor` (nullable string, required): Cursor for the previous page. Pass back as `ending_before` to step backward. `null` when no previous page exists.
- `refresh_cursor` (nullable string, required): Refresh anchor, the first row of this response. Pass back as `ending_before` to fetch what precedes it in the current sort order. On a newest-first sort those are the items that have appeared since; on any other sort they are the items that sort earlier, so refreshing such a list means re-fetching it instead. Non-`null` whenever `data` is non-empty; `null` only on an empty page. Distinct from `prev_cursor`.
