Posting

One request, every network. Each target can carry its own text, media and options.

You can cancel it before it goes out with POST /v1/posts/{id}/cancel.

Queued

With queue: true it takes the next free slot of the profile’s queue. Every account must belong to the same profile.

POST /v1/posts

curl -X POST "https://api.usecrier.com/v1/posts" \
  -H "Authorization: Bearer $CRIER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Tip of the day",
    "queue": true,
    "targets": [
      {
        "accountId": "acc_ig"
      }
    ]
  }'

const res = await fetch('https://api.usecrier.com/v1/posts', {

            }
        ]
    },
)
data = res.json()["data"]

Draft

With draft: true it is saved without posting or scheduling.

Text and media per network

Each target can replace the post’s text (content) and media (media), and carry its network’s options under the network’s key (instagram, youtube, tiktok…). See Network options.

POST /v1/posts

curl -X POST "https://api.usecrier.com/v1/posts" \

Statuses

Status	Meaning
`draft`	Draft, no date.
`pending_approval`	Waiting for an owner or admin to approve it. It does not go out until then.
`scheduled`	Scheduled or queued, waiting for its time.
`publishing`	Being sent to the networks.
`published`	Live everywhere. Each target has its `url`.
`partial`	Live on some, failed on others. Retry the failed ones with `POST /v1/posts/{id}/retry`.
`failed`	Live nowhere. Each target explains why in `error`.
`cancelled`	Cancelled before going out, or taken down everywhere.

Editing

While it is not live (draft, scheduled, failed or cancelled) you can change anything with PATCH /v1/posts/{id}. What you leave out stays; targets replaces the whole list.

PATCH /v1/posts/pst_7q1w0e

curl -X PATCH "https://api.usecrier.com/v1/posts/pst_7q1w0e" \
  -H "Authorization: Bearer $CRIER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "We open Friday at 10",
    "scheduledFor": "2026-10-30T10:00:00+01:00"
  }'

const res = await fetch('https://api.usecrier.com/v1/posts/pst_7q1w0e', {
  method: 'PATCH',
  headers: {
    Authorization: `Bearer ${process.env.CRIER_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "content": "We open Friday at 10",
    "scheduledFor": "2026-10-30T10:00:00+01:00"
  }),
});
const { data } = await res.json();

import os, requests

res = requests.patch(
    "https://api.usecrier.com/v1/posts/pst_7q1w0e",
    headers={"Authorization": f"Bearer {os.environ['CRIER_API_KEY']}"},
    json={
        "content": "We open Friday at 10",
        "scheduledFor": "2026-10-30T10:00:00+01:00"
    },
)
data = res.json()["data"]

With draft: false a draft goes out: now, at scheduledFor or in the queue.

Once live, only the text can change, and only on networks that allow it: X (Premium accounts, within the first hour), Facebook, LinkedIn, YouTube, Pinterest, Google Business, Telegram, Discord and Reddit.

POST /v1/posts/pst_7q1w0e/edit

curl -X POST "https://api.usecrier.com/v1/posts/pst_7q1w0e/edit" \
  -H "Authorization: Bearer $CRIER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Corrected text"
  }'

const res = await fetch('https://api.usecrier.com/v1/posts/pst_7q1w0e/edit', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.CRIER_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "content": "Corrected text"
  }),
});
const { data } = await res.json();

import os, requests

res = requests.post(
    "https://api.usecrier.com/v1/posts/pst_7q1w0e/edit",
    headers={"Authorization": f"Bearer {os.environ['CRIER_API_KEY']}"},
    json={
        "content": "Corrected text"
    },
)
data = res.json()["data"]

Approval

With requiresApproval: true the post stays in pending_approval: it does not go out until someone approves it. If the workspace requires approval (PATCH /v1/workspace with requireApproval: true, or from Team in the dashboard), members’ posts always go through it. Owners, admins and API keys skip it unless they ask for it.

POST /v1/posts

curl -X POST "https://api.usecrier.com/v1/posts" \
  -H "Authorization: Bearer $CRIER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "New collection",
    "scheduledFor": "2026-11-06T09:00:00+01:00",
    "requiresApproval": true,
    "targets": [
      {
        "accountId": "acc_ig"
      }
    ]
  }'

const res = await fetch('https://api.usecrier.com/v1/posts', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.CRIER_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "content": "New collection",
    "scheduledFor": "2026-11-06T09:00:00+01:00",
    "requiresApproval": true,
    "targets": [
      {
        "accountId": "acc_ig"
      }
    ]
  }),
});
const { data } = await res.json();

import os, requests

res = requests.post(
    "https://api.usecrier.com/v1/posts",
    headers={"Authorization": f"Bearer {os.environ['CRIER_API_KEY']}"},
    json={
        "content": "New collection",
        "scheduledFor": "2026-11-06T09:00:00+01:00",
        "requiresApproval": True,
        "targets": [
            {
                "accountId": "acc_ig"
            }
        ]
    },
)
data = res.json()["data"]

An owner, an admin or an API key decides with POST /v1/posts/{id}/review. Approved, it is scheduled for its date, goes to the queue if it asked for it, or goes out now if its date passed while it waited. Rejected, it goes back to draft with the note, and your webhook gets post.rejected.

POST /v1/posts/pst_7q1w0e/review

curl -X POST "https://api.usecrier.com/v1/posts/pst_7q1w0e/review" \
  -H "Authorization: Bearer $CRIER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "decision": "reject",
    "note": "Change the cover photo"
  }'

const res = await fetch('https://api.usecrier.com/v1/posts/pst_7q1w0e/review', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.CRIER_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "decision": "reject",
    "note": "Change the cover photo"
  }),
});
const { data } = await res.json();

import os, requests

res = requests.post(
    "https://api.usecrier.com/v1/posts/pst_7q1w0e/review",
    headers={"Authorization": f"Bearer {os.environ['CRIER_API_KEY']}"},
    json={
        "decision": "reject",
        "note": "Change the cover photo"
    },
)
data = res.json()["data"]

Editing it while it waits does not publish it: it stays pending. Its author can withdraw it with POST /v1/posts/{id}/cancel.

Recycle

A post that works can go out again on its own: every N weeks or months, as a new post. It stops at maxCopies or after until, and variations are used in turn so the text is not always the same.

PUT /v1/posts/pst_7q1w0e/recycling

curl -X PUT "https://api.usecrier.com/v1/posts/pst_7q1w0e/recycling" \
  -H "Authorization: Bearer $CRIER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "every": 2,
    "unit": "month",
    "maxCopies": 6,
    "variations": [
      "The autumn classic is back 🍂",
      "In case you missed it: our autumn classic"
    ]
  }'

const res = await fetch('https://api.usecrier.com/v1/posts/pst_7q1w0e/recycling', {
  method: 'PUT',
  headers: {
    Authorization: `Bearer ${process.env.CRIER_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "every": 2,
    "unit": "month",
    "maxCopies": 6,
    "variations": [
      "The autumn classic is back 🍂",
      "In case you missed it: our autumn classic"
    ]
  }),
});
const { data } = await res.json();

import os, requests

res = requests.put(
    "https://api.usecrier.com/v1/posts/pst_7q1w0e/recycling",
    headers={"Authorization": f"Bearer {os.environ['CRIER_API_KEY']}"},
    json={
        "every": 2,
        "unit": "month",
        "maxCopies": 6,
        "variations": [
            "The autumn classic is back 🍂",
            "In case you missed it: our autumn classic"
        ]
    },
)
data = res.json()["data"]

Each copy is a post of its own with recycledFrom, and your webhook gets post.recycled.
YouTube and TikTok do not allow repeated content: those accounts are left out of the copies.
Each account can have up to 10 posts recycling at once.
DELETE /v1/posts/{id}/recycling stops it; copies already created stay.

Metrics

GET /v1/posts/{id}/metrics returns impressions, reach, views, likes, comments, shares, saves and clicks, in total and per account. They arrive a few minutes after posting; until then it returns null. Each network reports its own: the rest are 0.

Account groups

Save account selections (for example "All of Acme") with POST /v1/account-groups and use them when importing a CSV or from the dashboard.

POST /v1/account-groups

curl -X POST "https://api.usecrier.com/v1/account-groups" \
  -H "Authorization: Bearer $CRIER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "All of Acme",
    "accountIds": [
      "acc_ig",
      "acc_li",
      "acc_x"
    ]
  }'

const res = await fetch('https://api.usecrier.com/v1/account-groups', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.CRIER_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "name": "All of Acme",
    "accountIds": [
      "acc_ig",
      "acc_li",
      "acc_x"
    ]
  }),
});
const { data } = await res.json();

import os, requests

res = requests.post(
    "https://api.usecrier.com/v1/account-groups",
    headers={"Authorization": f"Bearer {os.environ['CRIER_API_KEY']}"},
    json={
        "name": "All of Acme",
        "accountIds": [
            "acc_ig",
            "acc_li",
            "acc_x"
        ]
    },
)
data = res.json()["data"]

Taking down and deleting

POST /v1/posts/{id}/unpublish takes it down from every network, or only from accountId. Instagram and TikTok do not allow it through the API: delete it in the app.
DELETE /v1/posts/{id} deletes it from Crier. If it is still live, take it down first.
