IFrame

Embed LikeCoin button using <iframe>

Instructions

1. Construct an embedded URL according to the following format:

https://button.like.co/in/embed/{{LikerID}}/button?referrer={{referrer}}&type={{type}}

Parameter

Type

Required?

Description

LikerID

string

required

The author of the content

referrer

string

required

The source (canonical) URL of the content in encodeURIComponent() format (this also works as the content key)

type

string

optional

wp for WordPress site, omit for the others

For testing purpose, you may use button.rinkeby.like.co instead of button.like.co

In case of iframe sandbox, allow-scripts, allow-same-origin, allow-popups allow-popups-to-escape-sandbox, allow-top-navigation-by-user-activation, allow-storage-access-by-user-activation are needed for proper register/login functionality.

2 Embed the sample HTML and replace {{ src }} with the embed URL into your HTML

3 Include the CSS code​

4 (Optional) Update referrer via postMessage​

The LikeCoin button <iframe>'s src (especially the referrer param) should be updated to when the URL is changed. In case updating <iframe>'s src is not possible (e.g. for some SPA usecases), you may call postMessage() to the <iframe> with following payload to update the referrer.

{
action: 'SET_REFERRER',
content: { referrer: `${ newReferrer||window.location.href }` }
}, 'https://button.like.co'
