1. Introduction & acceptance
This Developer Agreement ("Agreement") is entered into between Verbleif B.V. ("Verbleif", "we", "us") and the person or organisation that registers as a developer or builds an integration on the Verbleif platform ("Developer", "you"). By creating a developer account, accessing the Verbleif API, or submitting an App to the Verbleif App Store, you accept this Agreement. If you accept on behalf of an organisation, you confirm that you are authorised to bind that organisation, and "you" refers to that organisation.
2. Definitions
- App: software, an integration or a service you build that connects to the Verbleif platform.
- API: the application programming interfaces, webhooks and related documentation Verbleif makes available.
- Verbleif Platform: the Verbleif applications, services and infrastructure operated by Verbleif.
- Client: an organisation that uses Verbleif and may install your App.
- End User: an individual who uses Verbleif or your App.
- Personal Data: any information relating to an identified or identifiable natural person.
- Scopes: the granular permissions that determine which data and actions your App may access.
3. Eligibility & developer registration
You must be legally able to enter into this Agreement and, where you act for an organisation, be authorised to do so. You agree to provide accurate company information, including your company name, contact email, phone number and website, and to keep it current. This information may be shown to Clients who are deciding whether to install your App.
4. Licence grant & scope of API access
Subject to this Agreement, Verbleif grants you a limited, non-exclusive, non-transferable and revocable licence to access and use the API solely to build, operate and support your registered App. You may not use the API beyond the Scopes granted to you, resell raw API access, or attempt to derive Verbleif's source code. All rights not expressly granted are reserved by Verbleif.
5. Acceptable use & fair use
You will use the API responsibly and within any published rate limits and quotas. You will not place an unreasonable load on the Platform, circumvent technical limits, scrape data outside your granted Scopes, or interfere with the Platform, Clients or other integrations. Verbleif may apply rate limiting, throttling or temporary restrictions to protect the stability and security of the Platform.
6. Data protection & privacy
You will comply with applicable data protection law, including the GDPR. Where you process Personal Data on behalf of a Client, you act as a processor and the Client as controller, and you will enter into any required data processing terms. You will process Personal Data only for the purposes the Client has authorised, apply data minimisation, and not transfer Personal Data outside the EEA without an appropriate safeguard. You will disclose your sub-processors where required.
7. Security requirements
You will protect all credentials, client secrets, API keys and tokens using industry-standard measures, and never expose them in client-side code, logs or public repositories. Webhook endpoints must use HTTPS and verify the signatures Verbleif provides. You will maintain reasonable security practices and notify Verbleif without undue delay, and in any event within 72 hours, after becoming aware of a security incident affecting Verbleif data.
8. Scopes, permissions & end-user consent
You will request only the Scopes your App genuinely needs and use the data obtained solely for the features the Client and End Users expect. You will honour permission grants and revocations, and stop accessing data when a Client uninstalls your App or withdraws consent. You will give End Users clear information about what your App does with their data.
9. Intellectual property & branding
Each party keeps all rights in its own intellectual property. Verbleif grants you no rights in its trademarks, except a limited right to use the Verbleif name and logo to indicate compatibility, in line with any brand guidelines we publish. You warrant that you own or have the rights to your App, its content, its name and its logo, and that they do not infringe the rights of any third party.
10. Confidentiality
You will keep confidential any non-public information Verbleif shares with you, including non-public API details, credentials, security information and roadmap information. You will use it only to exercise your rights under this Agreement, and protect it with at least the care you use for your own confidential information. This obligation survives termination.
11. App review, listing & content standards
Verbleif may review, approve, reject or remove any App or listing. All listing content, including the App name, introduction, description, logo, company information and support documentation URL, must be accurate, lawful and not misleading. You are responsible for keeping your listing up to date and for ensuring your App behaves as described.
12. Support & maintenance obligations
You will provide a valid support contact and a working Support Documentation URL, and respond to issues affecting Clients within a reasonable time. You will maintain your App so that it continues to work with supported versions of the API, and fix material defects that you become aware of.
13. Fees & commercial terms
Access to the API and the App Store is provided free of charge under the current version of this Agreement. There is no revenue share or developer fee at this time. If Verbleif introduces fees or commercial terms in the future, we will give you notice, and your continued use after they take effect will be subject to those terms.
14. Warranties & disclaimers
The API and Platform are provided "as is" and "as available", without warranties of any kind, whether express or implied, to the maximum extent permitted by law. Verbleif does not warrant that the API will be uninterrupted, error-free or compatible with every future version. You warrant that you will operate your App lawfully and in accordance with this Agreement.
15. Limitation of liability
To the maximum extent permitted by law, Verbleif is not liable for any indirect, incidental, special or consequential damages, or for lost profits, revenue, data or goodwill arising from your use of the API or this Agreement. Nothing in this Agreement excludes or limits liability that cannot be excluded or limited under applicable law.
16. Indemnification
You will indemnify and hold Verbleif harmless against any third-party claims, damages, liabilities and reasonable costs arising from your App, your use of the API, your content, or your breach of this Agreement or of applicable law.
17. Term, suspension & termination
This Agreement applies for as long as you access the API or maintain an App. Either party may terminate it at any time. Verbleif may suspend or terminate your access, or remove or take down an App, immediately if you breach this Agreement, create a security or legal risk, or harm the Platform or its users. On termination you will stop using the API and delete Verbleif data that you no longer have a basis to keep. Provisions that by their nature should survive will continue to apply.
18. Changes to the Agreement & API
Verbleif may update this Agreement and the API from time to time. Each version of this Agreement is identified by a version label. When we publish a material change, we may require you to accept the new version before you can publish or update an App; continued use after a change takes effect means you accept it. We aim to give reasonable notice of breaking API changes.
19. Governing law & dispute resolution
This Agreement is governed by the laws of the Netherlands. Any dispute arising from or relating to this Agreement will be submitted to the competent court in the Netherlands for the district in which Verbleif has its registered office, unless mandatory law provides otherwise.
20. Contact & notices
Legal notices to Verbleif must be made in writing and sent to Verbleif B.V., Jeverweg 2-4, 9723JE Groningen, the Netherlands, or by email to sales@verbleif.com. We may give you notices through the email address associated with your developer account, or by posting them on this page.
