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

To integrate a "Contribute" option directly on your website
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.
The widget will look better if it has some space, ideally the full page height & width
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):
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:
Some parameters can be used to customize the UI. See above
The simplest way to embed the contribution flow is by using the /donate URL (e.g. ). Just replace COLLECTIVE_SLUG by your collective slug below:
