    "description": "Έκδοση και διαβίβαση παραστατικών στο myDATA μέσω της **Novus Conceptus**, πιστοποιημένου Παρόχου Ηλεκτρονικής Τιμολόγησης της ΑΑΔΕ.\n\n## Πριν ξεκινήσετε\n\n1. Στις **Variables** της collection βάλτε:\n   - `apiKey`: το δοκιμαστικό API key σας (από το developer portal),\n   - `issuerVat`: τον ΑΦΜ με τον οποίο γραφτήκατε. Όλα τα παραστατικά εκδίδονται με αυτόν.\n2. Το `baseUrl` δείχνει εξ ορισμού στο **δοκιμαστικό** `https://provider-dev.timologisi.online`.\n   Για παραγωγή αλλάξτε το σε `https://provider.timologisi.online` (με το κλειδί παραγωγής).\n3. Και τα δύο περιβάλλοντα έχουν **Swagger UI στο `/index.html`**.\n\n## Σειρά εκτέλεσης\n\nΞεκινήστε από τον φάκελο «1. Ροή: το πρώτο παραστατικό» και τρέξτε τα αιτήματα με τη σειρά.\nΣε κάθε φάκελο τα αιτήματα είναι αριθμημένα: όπου ένα βήμα χρειάζεται κάτι από το προηγούμενο\n(MARK, UID, token υπογραφής), τα scripts το αποθηκεύουν **αυτόματα** σε μεταβλητές της collection.\n\nΗ **σημερινή ημερομηνία** (`{{today}}`) και **νέος ΑΑ** (`{{aa}}`) μπαίνουν αυτόματα πριν από κάθε κλήση.\nΣτο **Console** του Postman βλέπετε το `statusCode`, το MARK και τα σφάλματα της ΑΑΔΕ κάθε απάντησης.\n\n## Προσοχή\n\n- **Ένα παραστατικό ανά κλήση.**\n- Μέσω Παρόχου εκδίδονται **μόνο οι τύποι 1.1 έως 11.5**. Οι 12.x έως 17.x δεν διαβιβάζονται από Πάροχο.\n- **HTTP 200 δεν σημαίνει επιτυχία:** κοιτάτε το `response[0].statusCode`. `Success` ή `Offline` = εκδόθηκε.\n- Σε `Offline` **μην** το ξαναστείλετε: θα διαβιβαστεί αυτόματα.\n- Το ίδιο παραστατικό δεύτερη φορά δίνει σφάλμα ΑΑΔΕ `228`, με το MARK του αρχικού.\n- Κάθε κλήση χρεώνει credits (πεδίο `credits`).\n\nΤεκμηρίωση: https://developers.novusconceptus.com",
