Announcing comments API - access all comment information from a creator's content

This is some text inside of a div block.
  • Phyllo's Comments API is live for Instagram and YouTube, with support for other social channels coming soon.
  • The API returns comment text, publishing status, commenter username, and engagement data like likes and reply counts.
  • Audience sentiment and top-fan discovery are the two gaps Phyllo built the API to close, since most platforms do not expose that data.
  • Phyllo maps the API to 5 use cases: fan communities, influencer marketing, membership platforms, creator marketplaces, and media kits.
  • The endpoint extends Phyllo's Engagement API, and full request details sit in the docs.getphyllo.com developer guide.

At Phyllo, we are constantly looking for ways to empower developers who are building tools and applications for creators. The Comments API is a step along that path.

We realized that developers could derive immense value if they learn details about the commenter and the comments on a content thread. This information would be useful in -

  • Learning about the audience sentiment
  • Knowing who the top fans of a creator are (most platforms do not provide this information natively)

The Comments API is an extension of Phyllo’s Engagement API by which you can get access to all comment information for a creator’s content.

Developers can use the API to fetch the actual comment text, publishing status, username of the commenter, and engagement attributes such as the number of likes on the comment, number of replies to the comment, etc., and much more depending on the information different work platforms provide.

Comments from all connected social platforms are displayed in one place

Phyllo’s Comments API powers many use cases such as:

  • Creator Community/Fan communities: Creators may bring their top commenters to community pages based on comments and interactions
  • Influencer marketing platforms: Enable brands to discover influencers based on comments and influencer impact
  • Membership platforms: Creators pick the top fans and offer them special subscriptions
  • Creator marketplaces: Enable creators to invite their top commenters/fans to their exclusive workshops and access special content offerings
  • Media kits / Creator profile: Get the complete overview of top commenters along with their interactions around content

Our Comments API is now live and currently supports Instagram and YouTube. Support for other social channels is coming soon.

What is Phyllo's Comments API?

Phyllo's Comments API is an extension of the Engagement API that returns all comment information on a creator's content, including the comment text and who posted it.

Which platforms does the Comments API support?

Instagram and YouTube are supported now that the API is live, and Phyllo says support for other social channels is on the way, so you code against one interface.

What data does a comments API return for a creator's post?

You get the comment text, its publishing status, the commenter's username, and engagement attributes such as likes and replies, plus extra fields where a work platform offers them.

How do you find a creator's top fans from comment data?

Rank commenters by how often they comment and by engagement attributes like likes and replies. Most social platforms do not provide top-fan data natively, so it has to be derived.

Can comment data be used for audience sentiment analysis?

Yes. The raw comment text on a creator's content is the input sentiment analysis needs, and learning audience sentiment is one of the two reasons Phyllo shipped this API.

What can developers build with comment data?

Fan communities, influencer marketing platforms, membership subscriptions, creator marketplaces, and media kits all run on comments, from picking top fans to scoring creator impact.

Does the API show comments from every platform in one place?

Yes. Comments from all the social platforms a creator connects are displayed together, so you query once instead of wiring up Instagram and YouTube comment endpoints separately.

Where are the Comments API docs?

The list social comments operation is documented in Phyllo's developer guide at docs.getphyllo.com, under the API reference, with the request and response fields laid out.
