What is the best social media API for developers?
The best social media API depends on what you’re building. If you need to publish across multiple platforms from one place, go with a unified social media API that standardizes endpoints and data formats.
What is an API for social media?
A social media API is a set of endpoints that lets your app talk to platforms like Facebook, LinkedIn, or X. It allows you to publish posts, fetch data, and manage accounts programmatically instead of using the UI.
Who is this social media API plan built for?
The social media API plan is for developers, automation builders, and agency tech leads who need a clean publishing endpoint via REST API — without the overhead of analytics, AI Studio, or the full social media management suite.
How quickly can I get my first API key?
Under 5 minutes from signup. A streamlined 3-step onboarding (profile → role → connect accounts) takes you directly to your API Dashboard where you generate your first key immediately.
What happens when I hit my API request limit?
You'll receive an in-app alert at 80% usage and an email at 90%. Your dashboard shows live usage at all times. You can add 1,000 extra requests for $5 instantly from the billing page.
Are add-ons available on full-suite plans as well as the social media API plan?
Yes. Most add-ons (API requests, social accounts, media storage) are available across all plans. A few add-ons like AI image/video credits are only available on Standard and above. Each add-on is labelled with its eligible plans.
How do I generate and manage my API key?
Once you complete onboarding, you land directly on your API Dashboard. From there, click "Generate API Key" to create your key and secret. You can also revoke or regenerate your key at any time from the same screen. Note: your secret is shown only once at generation — copy it immediately and store it securely. In V1, one API key is supported per workspace; multi-key support is on our V2 roadmap.
What are the rate limits on the API Plan?
The API Plan includes 3,000 API requests per month by default. Your API Dashboard shows your real-time rate limit status at all times. You'll receive an in-app alert at 80% usage and an email notification at 90%. If you need more capacity, you can add 1,000 requests for $5 at any time from your billing page — with no upper cap on add-ons.
Which social networks can I publish to via the API?
The API Plan supports all major social networks available in ContentStudio — including Facebook, Instagram, LinkedIn, X (Twitter), TikTok, YouTube, Pinterest, Threads, Bluesky, and Google Business Profile. X (Twitter) posting is capped at 30 posts per day by default, with additional capacity available as a $5 add-on per 5 posts/day.
Does the API Plan work with Zapier, Make, n8n, and Pabbly?
Yes — all four are supported. You can connect ContentStudio to Zapier, Make (formerly Integromat), n8n, and Pabbly Connect out of the box using your API credentials. If your automation platform supports REST API calls via an HTTP module, it will work with ContentStudio's API as well. Integration guides and sample workflow templates are available in the API Dashboard under Quick Links.
How long is the free trial for the social media API, and what’s included?
The API Plan trial is 7 days, with no credit card required. You get full access to everything included in the plan — API Dashboard, key generation, publishing, content library, and all integrations. At the end of the trial, your account pauses; there are no automatic charges.
