TheCreatives Cave is an SMS gateway. Your product or console sends a request to TheCreatives Cave. The gateway checks the account, queues the message, delivers the SMS, and reports sent or failed. ### How do I send one SMS? POST /v1/messages with a bearer API key, a Philippine number in E.164 form such as +639171234567, the message text, and a sender id. The console Compose screen sends the same way. ### How do I send to many numbers at once? POST /v1/messages/bulk with a recipients list and one shared text. One request accepts up to 100 numbers. Each number becomes its own message, with its own sent or failed result. ### How much does an SMS cost? Each SMS segment is priced below ₱1 and taken from the account wallet. A message of 1 to 160 characters is one segment. After that, every 153 characters is another segment, up to 670 characters. A failed send is returned to the wallet. ### Which phone numbers can I send to? Numbers must be valid Philippine mobile numbers in E.164 format, beginning with +63. The message must be at least 10 characters and must not look like spam. ### What is a sender ID? A sender ID is the name the handset shows. Use "shared" for the platform sender, or apply for your own name. Sending with a name that is not registered is rejected. ### How do I know a message was delivered? The message status moves through queued, sending, sent, or failed. You can read it in the console or poll GET /v1/messages/{id}. If the account has a webhook URL, TheCreatives Cave signs the body with HMAC-SHA256 and posts the update there. ### Can several clients send at the same time? Yes. Each account submits on its own. The gateway accepts those requests together and sends them through a pool of workers, so one client does not wait for another client to finish typing. ### How do I open an account? Email hello@thecreativescave.com with your name, company, and how you plan to use SMS. The platform issues the sign-in. API keys are created inside the console after you sign in. ### Who do I contact? Email hello@thecreativescave.com for accounts, sender IDs, billing, and delivery questions.
