[e.voice](https://rejoose.com/knowledge-base/e-voice) 9 July 2025 # Which API should I use to collect carbon data for refurbished products? ## Use the e.voice API to track emissions from refurbished product sales. To collect carbon data for refurbished products you sell, you should use the e.voice API. This API connects to your ERP system and automatically generates an e.voice each time you invoice a customer. The e.voice includes the carbon footprint of the refurbished products listed on the invoice. **Note:** If you're collecting refurbishment-specific impact and avoided emissions data (rather than general product carbon data), see the article on[e.voice circularity](https://rejoose.com/knowledge-base/what-is-e.voice-circularity).   - [e.tool](https://rejoose.com/knowledge-base/e-tool#main-content) - [User guide](https://rejoose.com/knowledge-base/e-tool#user-guide) - [e.voice](https://rejoose.com/knowledge-base/e-voice) - [e.product](https://rejoose.com/knowledge-base/e-product#main-content) - [Getting started](https://rejoose.com/knowledge-base/e-product#getting-started) - [e.voice circularity](https://rejoose.com/knowledge-base/e-voice-circularity) - [e.hub & e.insights](https://rejoose.com/knowledge-base/e-hub-e-insights#main-content) - [User guide](https://rejoose.com/knowledge-base/e-hub-e-insights#user-guide) - [API](https://rejoose.com/knowledge-base/api) - [FAQ](https://rejoose.com/knowledge-base/faq#main-content) - [Partner FAQ](https://rejoose.com/knowledge-base/faq#partner-faq) - [End customer FAQ](https://rejoose.com/knowledge-base/faq#end-customer-faq) - [General](https://rejoose.com/knowledge-base/faq#general) - [Videos](https://rejoose.com/knowledge-base/videos#main-content) - [e.insights](https://rejoose.com/knowledge-base/videos#e-insights) - [e.tool](https://rejoose.com/knowledge-base/videos#e-tool) [![Icon\_web](https://rejoose.com/hs-fs/hubfs/Icon_web.png?width=49&height=49&name=Icon_web.png "Icon_web")](https://www.rejoose.com)   Copyright © 2025, Rejoose ApS
