# 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. Replace 'webpack' with your collective slug to generate your own. ## URL parameters The contribution flow supports many URL parameters to pre-fill the contribution. Example: . This link will bring you directly to the profile step of the contribution flow for webpack, with a monthly contribution of $66.66. | name | type | description | default | example | | ---------------------------------------------------------------------- | -------------------- | ------------------------------------------------------------------------------------------------------------------ | ------------------------------- | -------------------------------------------------- | | `amount` | amount | Default contribution amount | | `&amount=42.42` | | `quantity` | integer | Default number of units (for products and tickets only) | 1 | `&quantity=5` | | `interval` | interval | The contribution interval (must be supported by the selected tier, if any) | | `&interval='month'` | | `paymentMethod` | string | ID of the payment method to use.

Visitors will be able to contribute directly, by simply providing an email address. ![Embedded contribution on the website of an initiative](https://2931279126-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LWSZizTt4ZC1UNDV89f%2F-MTaMKR8Qppa7z-u_C0-%2F-MTaUZ_M6TRFpqqN3ttc%2Fimage.png?alt=media\&token=57be6cdd-bc03-4f1a-93e6-35f03cf72d13) ### General considerations * 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](#url-parameters) above ### Embed the default tier (Donate) 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: ```markup ``` ### Embed a specific tier 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`): ```markup ``` ### Embed an event ticket 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: > [https://opencollective.com/embed/mautic-conference-europe-4da0de72/contribute/general-access-ticket-32898](https://opencollective.com/embed/mautic-conference-europe-4da0de72/contribute/general-access-ticket-32898.)
