How to Schedule Social Media Posts with an API

De twee manieren om content te plannen

Upload-Post gives you two approaches for scheduling. You can set an exact date and time with the scheduled_date parameter, or you can let the system decide the best time by using the queue system. Beide work on any endpoint: video uploads, photo uploads, and text posts.

Optie A: Plan voor een specifieke datum en tijd

Add the scheduled_date parameter to any upload request. The format is ISO-8601, and you can schedule up to 365 days in advance.

curl -X POST https://api.upload-post.com/api/upload \
  -H "Autorisatie: Apikey jouw-api-sleutel-hier" \
  -F "[email protected]" \
  -F "user=mybrand" \
  -F "title=Coming soon... stay tuned!" \
  -F "platform[]=tiktok" \
  -F "platform[]=instagram" \
  -F "scheduled_date=2025-09-22T10:00:00Z" \
  -F "timezone=Europe/Madrid"

A couple of important details here. The date is in UTC by default, but you can pass a timezone parameter using IANA format (like Amerika/New_York, Europa/Londen, Azië/Tokio) so the post goes live at the right local time. This saves you from doing timezone math yourself.

When a post is successfully scheduled, the API responds with a 202 status and includes a job_id:

{
  "success": true,
  "job_id": "scheduler_job_abc123",
  "scheduled_date": "2025-09-22T10:00:00Z"
}

Keep that job_id because you\'ll need it if you want to edit or cancel the post later.

Optie B: Gebruik het queuesysteem

The queue is perfect when you want consistent posting without picking exact times. Instead of choosing a date, you set add_to_queue=true and Upload-Post assigns the next available time slot based on your configured schedule.

Je wachtrij instellen

First, configure your queue settings. You define which days and which time slots you want:

curl -X POST https://api.upload-post.com/api/uploadposts/queue/settings \
  -H "Autorisatie: Apikey jouw-api-sleutel-hier" \
  -H "Content-Type: application/json" \
  -d '{
    "timezone": "Amerika/New_York",
    "slots": [
      { "hour": 9, "minute": 0 },
      { "hour": 12, "minute": 30 },
      { "hour": 17, "minute": 0 }
    ],
    "days": [0, 1, 2, 3, 4]
  }'

This example publishes at 9:00 AM, 12:30 PM and 5:00 PM (New York time), Monday through Friday. You can define up to 24 slots per day.

Inhoud aan de wachtrij toevoegen

curl -X POST https://api.upload-post.com/api/upload \
  -H "Autorisatie: Apikey jouw-api-sleutel-hier" \
  -F "[email protected]" \
  -F "user=mybrand" \
  -F "title=Monday motivation" \
  -F "platform[]=tiktok" \
  -F "platform[]=instagram" \
  -F "add_to_queue=true"

Upload-Post will automatically assign this post to the next open slot. If it\'s Wednesday at 2 PM, the post will be scheduled for 5:00 PM that same day. If all Wednesday slots are full, it moves to Thursday at 9:00 AM.

Want to see what times are available before queuing content? Use the preview endpoint:

curl https://api.upload-post.com/api/uploadposts/queue/preview?count=10 \
  -H "Autorisatie: Apikey jouw-api-sleutel-hier"

This returns the next 10 available slots with their exact dates and times. You can request up to 50 at once.

Beheer van geplande berichten

Once content is scheduled, you have full control over it through the API.

Lijst alle geplande berichten

curl https://api.upload-post.com/api/uploadposts/schedule \
  -H "Autorisatie: Apikey jouw-api-sleutel-hier"

Returns an array of pending jobs with their job_id, scheduled_date, platform details and a preview URL of the content.

Bewerk een geplande post

Need to change the publish date or update the caption? Use a PATCH request:

curl -X PATCH https://api.upload-post.com/api/uploadposts/schedule/scheduler_job_abc123 \
  -H "Autorisatie: Apikey jouw-api-sleutel-hier" \
  -H "Content-Type: application/json" \
  -d '{
    "scheduled_date": "2025-09-25T14:00:00Z",
    "title": "Bijgewerkte bijschrift met betere hashtags"
  }'

Annuleer een geplande post

curl -X DELETE https://api.upload-post.com/api/uploadposts/schedule/scheduler_job_abc123 \
  -H "Autorisatie: Apikey jouw-api-sleutel-hier"

The post and its uploaded assets are removed immediately.

Een contentkalender bouwen met de wachtrij

Here\'s a practical workflow that many agencies use. You batch produce content on Monday, upload everything to the queue, and the system distributes it throughout the week automatically. No need to be online at 9 AM on Wednesday to hit the publish button.

This is especially powerful when combined with tools like n8n or Make.com. For example, you can set up a workflow where new files in a Google Drive folder automatically get added to the queue. Check out our Google Sheets planningssjabloon voor n8n for a ready made setup.

Our social media holiday calendar is also handy for planning content around important dates throughout the year.

Plannen met Python

from upload_post import UploadPostClient
from datetime import datetime, timedelta

client = UploadPostClient(api_key="your-api-key-here")

# Schedule a video for tomorrow at 10 AM Madrid time
publish_date = (datetime.now() + timedelta(days=1)).replace(
    hour=10, minute=0, second=0
)

response = client.upload_video(
    video_path="/path/to/video.mp4",
    title="Gepland vanuit Python",
    user="mybrand",
    platforms=["tiktok", "instagram", "youtube"],
    scheduled_date=publish_date.isoformat(),
    timezone="Europe/Madrid"
)

print(f"Gepland! Taak ID: {response['job_id']}")

Dagelijkse uploadlimieten per platform

When scheduling a lot of content, keep in mind that each platform enforces daily limits. These are rolling 24 hour windows per connected account:

The queue system respects these limits automatically and won\'t overschedule for any platform.

Veelgestelde vragen

Kan ik dezelfde inhoud voor verschillende tijden op verschillende platforms plannen?

Not in a single request, but you can send separate requests for each platform with different scheduled_date values. Or use the queue system, which distributes automatically.

Wat gebeurt er als een geplande post mislukt?

You\'ll get a notification through webhooks (if configured) with the error details. You can also check the status with the GET /api/uploadposts/status?job_id=your_job_id endpoint.

Kan ik planning combineren met de no-code tools?

Absolutely. Beide n8n and Make.com can send the scheduled_date or add_to_queue parameters through the HTTP request module. This means you can build a visual workflow that reads from a spreadsheet and schedules everything automatically.
