Le-techs Corporation (Headquarters: Shinjuku, Tokyo, President: Takashi Ogura) operating "ONE Digi API" has started integration with Yoom Inc. (Headquarters: Chiyoda, Tokyo, Representative: Shun Hatosaki) operating "Yoom".
This integration, through our first "no-code tool" connection, realizes flexible business construction that goes beyond the scope of traditional electronic contract services.
As a result, advanced reliability such as "electronic signatures" and "timestamps" can be incorporated into the existing business operations of any company without undergoing specialized system development.
◼︎ Service Integration Overview
With the integration of "ONE Digi API" and "Yoom", you can easily incorporate "electronic contracts" and "document certification" functions into the systems you normally use.
This integration automatically applies the "company's official seal (electronic signature/timestamp)" to documents simply by creating them in your usual tools.
It completely digitizes the analog process of "printing → stamping → mailing."
By eliminating paper exchange and creating a system where work is completed on a PC, daily administrative tasks become significantly easier.
◼︎ Integration Points
This allows for the complete automation of tasks such as "relying on manual stamping for reliability."
[Use Case 1] Automate stamping for large volumes of documents
It is particularly effective in situations where "a large volume of documents are issued," such as at the end of the month.
It eliminates tasks like "the system can output PDFs, but ultimately you open each file and paste the seal image" or "the number is large, so you end up batch printing and applying a real seal."
It is compatible with any document requiring an official seal, such as "payment notification letters," as well as "renewal notices" for real estate, "purchase orders" for construction, and "certificates of completion" for educational institutions.
Hundreds of stamping tasks can be completed with a single button.
It is possible to simultaneously increase document reliability and business speed while preventing human errors.
[Use Case 2] Automate the contract process from preparation to storage
It eliminates tasks such as "paying stamp duty," "printing two copies of the contract and binding them," and "mailing."
It can be applied to scenarios involving multi-party stamping, such as "contracts," "non-disclosure agreements (NDAs)," and "memoranda," digitizing the entire contract closing process.
It automates administrative tasks such as "document creation, mailing procedures, and folder sorting (storage)" that previously required human intervention.
*It is also possible to incorporate supervisor approval into the automation process, allowing for an operational flow where content is thoroughly reviewed internally before being sent to the other party.*
◼︎ What is Yoom
"Yoom" is a hyper-automation tool that automates various desk work by combining various automation technologies such as AI agents, APIs, RPA, and OCR.
No specialized knowledge such as programming is required; with intuitive operations alone, you can create AI workers that perform app integrations or specific tasks autonomously, allowing anyone to easily automate their own work.

◼︎ What is ONE Digi API
"ONE Digi API" is an API that resolves issues related to "reliability" and "administrative burden" concerning digital documents.
We can also propose how to increase sales, such as new customer acquisition and price increases, by enhancing the added value of your company's services, rather than just adding functionality.
Companies that are "looking to differentiate from competitors" or "improve customer satisfaction" are welcome to consult with us.
