A few things to know before you explore.
What is a selling API?
A selling API connects the information and actions involved in a sales workflow: lead records, CRM updates, conversations, tasks, and review decisions. SellingAPI.com explains those building blocks and gives you browser tools to explore them.
Can I use the app suite without an account?
Yes. The lead-score calculator, prompt builder, event sandbox, and conversation simulator run in your browser. No account or API key is required. Their examples are local demonstrations.
Does this site connect to Salesforce, LinkedIn, or OpenAI?
The supplied site contains integration guides and local demonstrations. A production connection requires the relevant provider account, approved access, and a server-side implementation. Start with the developer guide.
Where should I start?
If your records are scattered, begin with CRM integration. If prioritization is unclear, try the lead-score calculator. If conversations need structure, build a prompt and read the matching guide.
