Contribution flow
The contribution flow is how users support a collective on Open Collective. The Contribution flow can be directly accessed via this link: e.g. https://opencollective.com/webpack/donate
Replace 'webpack' with your collective slug to generate your own.

The contribution flow supports many URL parameters to pre-fill the contribution.
This link will bring you directly to the profile step of the contribution flow for webpack, with a monthly contribution of $66.66.

To integrate a "Contribute" option directly on your website
This feature is currently in a beta-test phase. If you face any issue or need assistance, you can send a message on Slack (#embed-contribution-flow channel)
The embed contribution flow is a way to integrate Open Collective on your own website. Visitors will be able to contribute directly, by simply providing an email address.
Embedded contribution on the website of an initiative

  • The widget will look better if it has some space, ideally the full page height & width
  • Some parameters can be used to customize the UI. See URL Parameters above

The simplest way to embed the contribution flow is by using the /donate URL (e.g. https://opencollective.com/babel/donate). Just replace COLLECTIVE_SLUG by your collective slug below:
<iframe src="https://opencollective.com/embed/COLLECTIVE_SLUG/donate" style="width: 100%; min-height: 100vh;"></iframe>

To embed a specific tier, you'll need to know its ID. For that, go to your profile page, click on "Contribute" for the tier you want to embed then check the URL. It should look like https://opencollective.com/COLLECTIVE_SLUG/contribute/TIER_SLUG-TIER_ID/checkout
From this URL, you can deduct the embedded one (prefix with embed and removes /checkout):
<iframe src="https://opencollective.com/embed/COLLECTIVE_SLUG/contribute/TIER_SLUG-TIER_ID" style="width: 100%; min-height: 100vh;"></iframe>

Embedding for event tickets uses the same route as regular tiers. you must make sure to remove the parent collective path and to include a slug. The slug can be anything, so if you're not sure feel free to put any value in there. For example, this path:
can be embedded as:
